  • How to create an Audio CD using C# or Java

    - by Elie
    I'm looking for an API that would allow me to create an audio CD from within a C# application. The CDs are to be created and closed in the same session (no rewrite required). Basically, my application locates files on behalf of a user, and, if a blank CD is present in the drive, creates an audio CD for the user. If no CD is present, it checks to see if there's a USB drive attached and copies the files there (this part I already know how to do). I would prefer to write this application in either C# or Java, as I'm most comfortable with those, but I don't know how hard it would be to create CDs using either language. There are several other questions here that deal with regular CDs, but I didn't see any discussing audio CDs.

  • Recording Audio through RTMP/Rails

    - by Lowgain
    I am in the process of building a rails/flex application which requires audio to be recorded and then stored in our amazon s3 account. I have found no alternative to using some form of RTMP server for recording audio through flash, but our hosting environment will not allow us to install anything like FMS, Red5, etc. Is there any existing Ruby/Rails RTMP solution that will allow audio recording? If not, is it possible for Rails to at least intercept the RTMP stream and then I can hope to reference red5 or something for parsing the data (long shot, I know)? The other alternative I can think of is hosting a red5 server on another host and communicating with our rails app once the saving/uploading is done, which is not preferred. Am I going to have any luck here?

  • Audio input via HTML5?

    - by tibbon
    We have a VoIP application imVOX, and we are looking at various ways of expanding our reach. Part of that is writing an HTML5 application, but it requires the use of audio input from the browser (and also push to talk buttons from the browser, even if another app is focused). On the audio side, with HTML5 is there any way of taking audio input from the browser to compress and send to our servers? I know with Flash such is possible, but we're trying to avoid flash for mobile compatibility and generally looking toward the future.

  • iPhone audio Filter Question

    - by Joe
    Okay, I am going to try to make this totally not a "plz send teh codez kthxbai" I am considering an app which takes sound (eventually an audio track) and applies an audio filter to it. So I can play sounds with AudioServicesPlaySystemSound via AudioToolbox framework just fine. What I need is a very simple example of how I might take a sound and apply (for instance) midrange boost etc. Actually the kind of alteration is irrelevant -- if I can get my head around how the alteration is done I can figure out the rest. I am just finding both docs and examples of altering audio in code to be very scarce. Thanks for any help!

  • iSCSI timeouts under high load

    - by Antonio
    I have two servers connected via Gigabit Ethernet. One is iSCSI target, the second one is initiator. When I run mkfs.ext4 at initiator, after a while disk IO slows down critically. In the target host I can see the following in syslog: Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 119668c 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 119668c 6 Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 119668d 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 119668d 6 Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 119668e 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 119668e 6 Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 1196696 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 1196696 6 Sep 14 09:40:03 sh11 tgtd: abort_task_set(1139) found 119669e 0 Sep 14 09:40:03 sh11 tgtd: abort_cmd(1115) found 119669e 6 Sep 14 09:40:04 sh11 tgtd: abort_task_set(1139) found 119669f 0 Sep 14 09:40:04 sh11 tgtd: abort_cmd(1115) found 119669f 6 And load average grows to 12 or even more: # uptime 12:37:00 up 23 days, 13:25, 1 user, load average: 12.00, 7.00, 4.00 CentOS 6.3 tgtd 1.0.24 Intel Pentium 4 2.4GHz 1Gb RAM 2Tb WD Cavlar Green SATA 2.0 #lspci 00:00.0 Host bridge: Intel Corporation 82845G/GL[Brookdale-G]/GE/PE DRAM Controller/Host-Hub Interface (rev 02) 00:01.0 PCI bridge: Intel Corporation 82845G/GL[Brookdale-G]/GE/PE Host-to-AGP Bridge (rev 02) 00:1d.0 USB controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #1 (rev 02) 00:1d.1 USB controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #2 (rev 02) 00:1d.2 USB controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) USB UHCI Controller #3 (rev 02) 00:1d.7 USB controller: Intel Corporation 82801DB/DBM (ICH4/ICH4-M) USB2 EHCI Controller (rev 02) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev 82) 00:1f.0 ISA bridge: Intel Corporation 82801DB/DBL (ICH4/ICH4-L) LPC Interface Bridge (rev 02) 00:1f.1 IDE interface: Intel Corporation 82801DB (ICH4) IDE Controller (rev 02) 00:1f.3 SMBus: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) SMBus Controller (rev 02) 00:1f.5 Multimedia audio controller: Intel Corporation 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 02) 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV200 QW [Radeon 7500] 02:01.0 Ethernet controller: D-Link System Inc DGE-530T Gigabit Ethernet Adapter (rev 11) (rev 11) 02:02.0 RAID bus controller: VIA Technologies, Inc.

  • Legality of ripping DVD audio

    - by Smashery
    I want to buy several live music DVDs, but I also want to be able to put the music in my playlists. It seems ridiculous that I should also have to buy the Live CD version. Is it legal (particularly under Australian law) to rip the audio?

  • Alternatives to musicbrainz picard -audio-fingerprinting tagging services [closed]

    - by Journeyman Geek
    Possible Duplicate: Auto-tagging MP3s I'm currently using musicbranz picard to tag files that don't have any usable tagging information. For some reason, currently none of the files I trying to ID seem to be identified, despite some of them them being artists who are almost certainly on musicbrainz. So, I'm looking for something that uses an alternate database and does the same thing - to identify unknown music files off an audio fingerprint. Windows is preferred, but I would be fine with any of the big 3 OSes (Windows/Linux/OS X).

  • Software that will extract the individual audio channels from a WMA file

    - by typoknig
    I have a 6 channel WMA file and I would like to extract each of those 6 channels into its own mono WAV file. This is a simple task with AC-3 audio files, but apparently not with WMA. I could re-encode the WMA as an AC-3 then extract the streams, but I want lossless solution. Please only confirmed solutions. I have put a lot of time into searching for a solution and have had my fill of "try this" and "this might work".

  • Streaming audio/video in a publicly-hosted server increases bandwith usage

    - by Eka
    I have a website hosted in a public server (withoud any streaming content) ,using public hosting instead of private because its cheaper. But in public hosting their are limitations when compared to private hosting such as monthly bandwidth usage (1 GB), disk space, cpu usage etc. I am planning to embedd videos and audios (from other websites like youtube) to my already existing website. My question is if a client streams a embedded video/audio (hosted in another website) from my website any change in bandwidth occurs.

  • How to right click and play audio folder on Windows Media Player 12

    - by Mehper C. Palavuzlar
    It's always been hard for me to add a music folder with subfolders to Windows Media Player's playlist. I double click a file in the folder (or click on WMP shortcut), WMP opens, and I drag the other files or folders manually to the playlist. Isn't there an option to add a right-click context menu item that can automatically add all audio contents in a folder (with subfolders) to WMP playlist?

  • Exchange 2010 DAG + VMWare HA = no support?

    - by Dan
    We currently have an Exchange 2003 clustered environment (two machine cluster) that we're looking to upgrade to 2010. We recently purchased a VMWare virtualization environment (three Dell R710's with an EMC NS-120 serving up NFS datastores - iSCSI is available) that we wish to use for this new environment. I'm seeing that Microsoft does not support Exchange 2010 DAGs with a virtualization high availability solution (see links below). I would like to utilize the DAG to ensure the data stays available if one host goes down, and HA to ensure that if the physical host goes down, the VM will come back up on the other available host. Does anybody know why MS does not support this? VMWare HA will only restart the VM if it is hung/down - I don't see any difference between this and restarting the physical box if someone pulled the power... Will we only run into issues with support if it has something to do with HA/DAG failover or will they see we have HA and tell us to put it on a physical box even if it has nothing to do with HA? If we disable HA for these VM's will that satisfy them on a support case? Has anybody set up an Exchange 2010 DAG on VMware with HA enabled? Will they have any issues with using an NFS datastore? We have much greater flexibility on the EMC with NFS vs iSCSI, so I would prefer to continue utilizing that. Thanks for any input! http://www.vmwareinfo.com/2010/01/verifying-microsoft-exchange-2010.html Take a look at the second image under "Not Supported" http://technet.microsoft.com/en-us/library/aa996719.aspx "Microsoft doesn't support combining Exchange high availability solutions (database availability groups (DAGs)) with hypervisor-based clustering, high availability, or migration solutions. DAGs are supported in hardware virtualization environments provided that the virtualization environment doesn't employ clustered root servers."

  • Oracle Application Server Performance Monitoring and Tuning (CPU load high)

    - by Berkay
    Oracle Application Server Performance Monitoring and Tuning (CPU load high) i have just hired by a company and my boss give me a performance issue to solve as soon as possible. I don't have any experience with the Java EE before at the server side. Let me begin what i learned about the system and still couldn't find the solution: We have an Oracle Application Server (10.1.) and Oracle Database server (9.2.), the software guys wrote a kind of big J2EE project (X project) using specifically JSF 1.2 with Ajax which is only used in this project. They actively use PL/SQL in their code. So, we started the application server (Solaris machine), everything seems OK. users start using the app starting Monday from different locations (app 200 have user accounts,i just checked and see that the connection pool is set right, the session are active only 15 minutes). After sometime (2 days) CPU utilization gets high,%60, at night it is still same nothing changed (the online user amount is nearly 1 or 2 at this time), even it starts using the CPU allocated for other applications on the same server because they freed If we don't restart the server, the utilization becomes %90 following 2 days, application is so slow that end users starts calling. The main problem is software engineers say that code is clear, and the System and DBA managers say that we have the correct configuration,the other applications seems OK why this problem happens only for X application. I start copying the DB to a test platform and upgrade it to the latest version, also did in same with the application server (Weblogic) if there is a bug or not. i only tested by myself only one user and weblogic admin panel i can track the threads and dump them. i noticed that there are some threads showing as a hogging. when i checked the manuals and control the trace i see that it directs me the line number where PL/SQL code is called from a .java file. The software eng. says that yes we have really complex PL/SQL codes but what's the relation with Application server? this is the problem of DB server, i guess they're right... I know the question has many holes, i'd like to give more in detail but i appreciate the way you guide me. Thanks in advance ... Edit: The server both in CPU and Memory enough to run more complex applications

  • Any screen capture software that captures webcam, microphone inputs too ?

    - by mohanr
    I am going to conduct a user study. Apart from capturing the screen while the user is interacting with the system, I also want to capture the video/audio of the user. Is there any software that in addition to capturing the screen also overlays it with the webcam/microphone inputs. The goal is to capture the complete experience of the user: key/mouse interactions with the system along with their facial/vocal responses. I know that I can maybe run a screen-capture software and also run a software for capturing webcam audio/video alongside and try to sync/overlay both these streams with timestamps. But I am going to be dealing with probably several hundred hours of data. So I am looking for a tool that can streamline the process for me amap and help me keep my sanity at end of the process. Thanks,
