• Convert a cassette tape recording to digital format

  - by Electric Automation

  Has anyone been successful with transferring audio cassette tape recordings to a digital format? I would like to preserve old cassette tape recordings of my grandparents to some digital format: MP3, WAV, etc... The quality of the tapes are mediocre. I think I can handle the quality restoration but getting the audio from tape to digital is my question. Below is a list of the hardware that I can work with: Cassette Deck: I have a Technics stereo cassette deck model RS-B12. It has separate left and right IN and OUT RCA type jacks on the back. In the front it has a headphone phono jack, plus left and right mic input phono jacks. On the computer side: -I have a Windows Vista PC with no additional software other than what came with the machine from Costco. No sound editing software that I can see. There is no sound card on the PC. On the front panel there is a mini-phono mic input jack and there are several different types of in/out mini-phono jacks on the back. In addition, USB and Firewire. I also have access to a new (2009) iMac with a mini-phono input jack for a powered mic or other audio source and GarageBand that has come with the computer. In addition, USB and Firewire. What are my options for getting these cassette recordings into a digital format? Whats the best format? What sort of wires would I need and will I want to utilize the USB or Firewire or can I simply use the audio inputs on the PC (or Mac) to receive the audio stream?

• No headphone or speakers plugged in - Windows 7 issue

  - by Amit Ranjan

  I am facing a wierd issue between my sound card driver and Windows7(any edition). I have a sony vaio notebook (VPCEB24EN). Two days ago, on start I got diabled wifi, charging and speakers. Then I restart the PC and everthing worked fine. Later on I again restarted my machine, and then I found the my speakers were not working. I thought, restart will work. I restarted many more times but it did'nt work. I searched google and found that , it might be due to : 1. Hardware is not switched on from bios. 2. No hardware. 3. overriding 64-bit drivers with 32-bit drivers. To make it working, I restored my laptop from scratched, but while restoring pc, the realtek HD drivers, it gave me an error 505. I then formatted the drive and installed Win7 Ultimate 32bit (With PC was, Win7 64-bit Home Basic). I got lots of yellow exclamation in device manager, thinking now this will resolve my issue. But Even after the installing all drivers on a fresh installation, I was still with the same position. A red cross on speaker- No Speakers or Headphone plugged in. Please Note: My Laptop is Vaio , E Series, VPCEB24EN. Audio : Intel® High Definition Audio compatible but accepts Realted Audio. While using BIOS Agent, I got Intel Chipset 5 Series Audio Adapter and ATI RV370 Audio adapter found on my board. Installed is Win7 32bit Ultimate. factory default was Win7 64-bit Home Basic Memory: RAM 3GB/ 320GB HDD Display : ATI Mobility Radeon™ HD 5145 Graphics

• Virtual Microphone and skype

  - by Dario

  I need to have at least one microphone on Windows to make Skype calls, but i have a VPS with Windows 2003 server with no audio device. I googled a lot and finally i found something called "Virtual Audio Cable", a tool to install virtual audio drivers ( http://software.muzychenko.net/eng/vac.html ). I tried many times but i couldn't get this driver work, so i'm asking if someone know a similar solution, i mean a virtual microphone or a way to make skype working without any microphone. Thanks all!

• DVD playback with Windows Media Player 11 works fine, but when copied to HDD and then played back, t

  - by stakx

  I have several DVDs with short documentaries on it. Since the notebook I'm using (a Dell Latitude E6400) has only one DVD drive, and I might play back those short movies very often, I thought of copying them to the HDD and playing them back from there. However, I've run into a problem, namely stuttering audio. Problem description: When I play back these movies directly from DVD (with Windows Media Player 11 under Windows Vista), everything works fine. Smooth video, no significant audio problems (only the occasional click). But as soon as I copy any of these DVDs to the HDD and try to play them back from there (e.g. using the wmpdvd://drive/title/chapter?contentdir=path protocol, I get stuttering audio — audio playback sounds like a machine gun for a third of a second or so, approx. every 8 seconds. I have tried converting the VOB files from the DVD to another format (ie. ripping), but that resulted in a noticeable downgrade of picture quality. Therefore I thought it best to keep the files in their original format, if possible. Still, I suspect that the stuttering audio is due to some (de-)muxing problem, and that changing the file format might help. (After all, video playback is fine; therefore I don't think that the hardware is too slow for playback.) Only thing is, I don't know how to convert the VOB files to another Windows Media Player-compatible format without quality loss. I hope someone can help me, or give me further pointers on things I could try out to get HDD playback to work without the problem described. Some things I've tried so far, without any success: VOB2MPG, in order to convert the .vob file to a .mpg file. But that changes only the A/V container, not the content. No re-encoding takes place at all. Re-encoding with MPlayer/MEncoder. Lots of quality loss there, and I frankly haven't got the time to test all possible settings combinations available. Disabling all plug-ins, equalizers, etc. in Windows Media Player. Disabling all hardware acceleration on the audio playback device. Further info on the VOB files I'm trying to playback: The video format is MPEG ES, PAL 720x576 pixels @ 24/25 frames per second. The sound stream is uncompressed PCM, 16-bit stereo @ 48kHz. (Might it help if I somehow re-encoded the sound stream at a lower resolution, or as an MP3? If so, how would I do this without changing the video stream?) P.S.: I am limited to using Windows Media Player (11). (I previously tried MPlayer btw., but the video playback quality was surprisingly bad.)

  I have a video that I need to pass on to some of my friends but it has very low audio volume. How can I boost the audio volume in this video so that it has a similar level as my other videos? Is there a video converter that can boost the audio volume?

• Setting Up a Virtual Sound Device To Stream Output via TCP/IP

  - by Martindale

  I'm interested in installing a custom driver / device that will open a socket (or listen) and stream audio via TCP/IP in both Windows and Linux. I would like to be able to specify this device as my "Output" for specific applications so that I can route my audio through a completely unique machine (for example, in complex Synergy setups where my headphones might be connected to one machine, but audio is being generated by another.) In Linux, I expect this to be very easy, but I anticipate having to install a custom driver in Windows.

• Soundtest works, but no other sounds and windows starts very slowly

  - by Kristian Kari

  So suddenly all sounds on my computer stopped working expect the sound test works, but when I go to control panel and audio it says there's no audio device. And audio players and audio on website doesn't work either. and Also windows starts very slowly. I'm not sure if this helps but I'll tell what happened before this. I downloaded this program from a little shady website, I hesitated and for a good reason I guess cos the moment I finished downloading it, my antivir detected it as unwanted program and put it on quarantine. I thought everything was fine, but had some problems with program (won't go to details about it cos it's not really related to audio) so rebooted the computer and I was suprised that windows started really really slowly. It took like 5 mins to load the desktop such. After that I noticed the sounds were missing, I immediately deleted the program since I thought it was causing the problem. But it didn't change much. I tried to find the solution with no success and now I'm just scanning again my computer. I'd be thankful if anyone would be able to help me. I might have left a thing or ten things out, so feel free to ask. oh and I'm using windows xp

• How can I automatically lower Spotify playback volume when my Video Editing program makes a sound?

  - by Mark Major

  I'd like to listen to Spotify while I am video editing. This is just casual listening - nothing to do with the editing work. How can I automatically fade out the volume of Spotify when my video editing program plays audio? I often need to hear the video editing audio without the distraction of Spotify playing over the top, but the video editing playback is too on/off/on/off to switch Spotify audio manually each time. Without background music, I get really sick of the repeated playback of the audio clips with only silence inbetween. I suppose what I needd is an app that monitors sound output from 'App A' and reduces the sound output from all others (Apps B, C, D, etc) when something is played.

• Data CD for audiobooks?

  - by Marco7757

  I'm trying to burn my .mb4-audiobook files to a CD. I was impressed by the compression-rate (10 hours of audiobook within 150MB?!). The problem now is, that I cannot burn it as an audio CD as these allow only about 80 minutes of audio (audiobook is about +10 hours). I burned them as a data CD now. It works, but, of course, the downside of a data CD is, that not every player (e.g. car, stereo) can play data CDs. What can I do? I don't want to waste 100 CDs on such a simple problem ... is there any way to burn an audio CD? I mean, just regarding the filesize this shouldn't be a problem, shouldn't it? Why is an audio CD only able to play up to 80 minutes?

• Adding audio channel using ffmpeg

  - by Raj

  Hi all, I am working on ffmpeg and trying to add a audio stream on the fly. I am using AudioQueues and I get raw audio buffer. I am encoding audio with linear PCM and hence the audio I get will be of raw format, which I know ffmpeg does accept it. But I cannot figure out how. I have looked into AVStream, where in we have to create a new stream for this audio channel but how do I encode it to a video which is already initialized in another AVStream structure. Overall, I would like to have an idea of the architecture of ffmpeg. I found it difficult to work since it is least documented. Any pointers or details are appreciated. Thanks and Regards, Raj Pawan G

• What is the String 'volumeName' argument of MediaStore.Audio.Playlists.Members.getContentUri referri

  - by Brett

  I am wanting to query the members of a given playlist. I have the correct playlist id, and want to use a managedQuery() to look at the playlist members in question. What I have is this: private String [] columns = { MediaStore.Audio.Playlists.Members.PLAYLIST_ID, MediaStore.Audio.Playlists.Members.TITLE, }; Uri membersUri = MediaStore.Audio.Playlists.Members.getContentUri(volume, playlistId); Cursor tCursor = managedQuery(membersUri, columns, null, null, null); I don't know what the volume argument needs to be. I've tried this: MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI.toString() for the "volume" argument. That gives me back a valid content URI that looks like: content://media/external/audio/playlists/2/members However, my cursor comes back null. I probably am way off base -- I know what I want to do is very simple.

• Core Audio sound driver has an error

  - by Raj More

  I have been using Virtual DJ on my machine. The setup is where I want audio to play over the headphones and use a USB sound card to play audio into my headphones so I can listen to music before I play it for everybody. However, the last time I tried, I got an error message saying "Error in the sound driver of Core Audio. Your sound card is probably not connected, or the settings are incorrect". If I use the headphone by themselves, the USB sound card by itself, or my speakers by themselves, they all work individually. How do I go about figuring out what's wrong here?

• Realtek HD Audio 5.1 Optical Input (from Xbox 360)

  - by Shevek

  I'm trying to connect up my Xbox 360 digital audio to my 5.1 speakers via my PC (my LCD has dual input, DVI for the PC, D-SUB for the Xbox). The motherboard has a Realtek ALC888 chipset and I have a 5.1 speaker system connected via 3 x 3.5mm jacks (FR/FL, RR/RL, C/LFE) and I get full 5.1 output from the PC. I have connected the optical audio cable from the Xbox to the Optical In on the motherboard's backplate. With the Xbox in Digital Stereo mode I get 2 channel audio from the Xbox, through the PC, to the speakers. With the Xbox in Dolby Digital 5.1 mode I get no sound at all. I have the latest Realtek drivers installed in Win 7 32-bit. Questions: Is it possible to use the full 5.1 DD from the Xbox? If so, am I missing some option(s) in the Realtek setup? Do I need some other piece of software to do this? (AC3Filter or FFDShow perhaps) Many thanks

• How to create a virtual input in windows from an audio stream

  - by Brian

  Great to find this forum full of knowledge. I was wondering if anyone knew of an application or other work around to create a virtual input device in windows. I have a IP cam app on my android phone, that I would like to use for skype webcam. It comes with a port for getting the video feed into skype, and that works great. However, the only audio available, is a OGG stream. Both video and audio work great with media players such as VLC etc, but ot with skype, since skype only works with windows input devices. Is there such software outthere, in which I could simply name my audio stream address, and pipe that to a virtual input device to allow skype to find it?

• Burn iTunes playlist to Audio Image

  - by MikeHoss

  I have Snow Leopard on an early model MacBook Pro. The CD Drive has been giving me fits the last few months -- I stick a blank CD in it, and it claims it's bad and spits it out. I can go through a pile of brand-new CD's and it will choose 1 out of 7 that it wants to use, even though all the CD's come from the same package. The rejected CD's work fine on a Linux machine I have. I need to burn an audio CD from iTunes and my thought was: Burn playlist to audio CD Image file (Red Book image?) Copy ISO file to Linux Machine Use Linux machine to burn audio image to a CD But looking around, it doesn't seem that iTunes on OSX will support this. I was wondering if anyone else has accomplished this.

• Forwarding audio like X in SSH

  - by Akilan

  While it is possible to use X applications remotely by using -X switch in ssh, the sound is being played in remote machine's speaker only. For example if I view a film in VLC/Totem only video is visible and I can't hear the audio. Is there a way to forward audio too? [without digging through Pulse-audio's setup, I mean; Like how ssh understands X forwarding by itself.] I have tried this only in Ubuntu (in various Ubuntu versions from 9.10 through 10.10), if that helps.

• After interruption, delayed audio route change notifications when recording

  - by Frank Shearar

  My iPhone application requires that I know when a user has/has not plugged in her headphones. That's easy. AudioSessionAddPropertyListener with a callback listening to kAudioSessionProperty_AudioRouteChange. I write logs with NSLog as things happen. User plugs the headphones in? Get a notification, and a line in the gdb console. User unplugs the headphones? Ditto. At the same time I'm sensing the noise level of the environment by starting a recording audio queue. This, too, works great: I can get the mic noise level and listen for audio route changes just fine. What I find is that after an interruption, and I've reactivated the audio session and restored the audio category to kAudioSessionCategory_RecordAudio, the audio route notifications go a bit haywire. When I plug in the headphones, I see no notification. When I unplug the headphones I see BOTH the "plugged in" notification AND the "unplugged" notification, in rapid succession. It's like the "plugged in" notification's delayed and, when the "unplugged" notification arrives, the queue of pending notifications is flushed. What am I doing wrong? How do I correctly restore the audio session to get timeous notifications? EDIT: iPhone OS 3.1.2, running on an iPhone 3G. I'm running a program compiled with the 3.0 SDK (from within XCode 3.1.2).

• how to play an audio soundclip when a nib is loaded - welcome screen - xcode

  - by Pavan

  I would like to do the following two things: 1) I would like to play an audio file qhen a nib is loaded 2) After that i would like to switch views when the audio file has finished playing. This will be easy as i just need to call the event that initiates the change of view by using the delegate method -(void) audioPlayerDidFinishPlaying{ //code to change view } I dont know how to to play the audio file when a nib is loaded. Using the AVFoundation framework, I tried doing the following after setting up the audio player and the variables associated with it in the appropriate places i wrote the following: - (void)viewDidLoad { [super viewDidLoad]; NSString *soundFilePath = [[NSBundle mainBundle] pathForResource: @"sound" ofType: @"mp3"]; NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: soundFilePath]; AVAudioPlayer *newPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL: fileURL error:nil]; [fileURL release]; self.player = newPlayer; [newPlayer release]; [player prepareToPlay]; [player setDelegate: self]; [player play]; } Although this does not play the file as the viewdidload method gets called before the nib is shown so the audio is never played or heard. What do i need to do so that i can play the audio file AFTER the nib has loaded and is shown on the screen? can someone please help me as ive been working on this for 3 hours now. Thanks in advance.

• Xaudio2 XAPO Effects

  - by Jason Champion

  I've been working with XAudio2. After looking at the samples, example code, and sparse documentation available from Microsoft and the MSDN, I've found that there aren't any easy-to-find resources on creating and using XAPO effects, nor any XAPO effects produced by third parties that I can download and/or buy. What it looks like is that if I create an app that uses XAPO effects, I'll have to create them all myself because there's no community of existing applications like there is with technologies like Apple's AU or Steinberg's VST. Is this true, or are there others using XAudio2 and XAPO and I just haven't found them? Is there a place to ask programmer-support-related questions about XAudio2 and related technologies (or is this the best destination)? The best I've found so far are the XNA forums, which are game-specific and sparsely populated in the audio area.

• Podcast Best Practices - Page Development & Monetization Considerations

  - by Christopher Ickes

  Our current podcast page has show notes and a link to download an mp3 of our podcast. We were advised to add an audio player to stream the file live from our website. The thought being this would improve time spent on our site and allow for greater advertising dollars. Is it better to have a page with show notes, an mp3 for download AND also stream the podcast live OR just stick to the show notes & mp3 download? Does anyone see any affect on advertising revenue, either way?

• Aw, Snap! in Google Chrome [on hold]

  - by D. S. Schneider

  Just wondering if anyone else's experiencing the "Aw, Snap!" bug in Google Chrome. I'm developing a brand new engine which occasionaly triggers this bug and as far as I know, there's nothing one can do to find out what actually triggered the issue. I've also tested my engine with Firefox, which runs just fine. Anyway, just wanted to know if someone else is facing this while developing games for Google Chrome and has a clue about what can be done to avoid it. I'm using plain JavaScript and the audio and canvas elements from HTML5. Thanks!

• What makes game sound effects "good"?

  - by you786

  I'm making a small game, and I've found some free sound effects that I'd like to use. The issue is that I can't get the sound effects to sound like they "belong" in my game. I don't know what to look for that can make sound effects match the rest of my game style. I have some ideas on what affects the meshing of audio with graphics. For example, I have a feeling that the current SFX I may be too "realistic" for my graphical style, which is pretty cartoon-like. Also, is there a golden standard for what volume various SFX should be at? (for example, I am thinking that footsteps or other common sounds should be at barely audible volumes, while enemy deaths or something that is a "big deal" should be louder). I found a similar question about graphics, I'm looking for a similar response with sound effects.
