What sort of mime type should I be using to email a .avi file from an automated python script? There are specific ones for audio/images, but not video afaik.
I am making a project where i am drawing waveform of an audio file in C#. Currently I am using mouse drag and drop for a part of waveform selection. But now i want that the waveform should also be selected by using following:
click at a point
press shift and click again on another point.
I dont have much knowledge about keyboard events. So need help in this.
I was wondering if someone could point me to a good tutorial or show me how to graph the amplitude from a bytearray. The audio format I am using is: ULAW 8000.0 Hz, 8 bit, mono, 1 bytes/frame.
I'm trying to use the gdx-audio extensions, but am having trouble decoding mp3s. It works, but very slowly!! A 10-second file is taking 6.57 seconds to decode :( Here is the method:
public void decode() {
Mpg123Decoder decoder = new Mpg123Decoder(externalFile);
short[] sampleArray = new short[1024];
// read until we reach the end of the file
while (decoder.readSamples(sampleArray, 0, sampleArray.length) > 0) {}
}
Can anyone tell me why this is taking so long?
Do you know a framework for making presentations using only HTML5 and javascript technologies?
I'm not talking about "export" features of various presentation software (powerpoint or OOo presentation).
Some requirements for the presentations made with this "framework":
take advantage of the latest HTML5 features (audio, video, canvas?)
same with CSS3 (font support, gradient, shadows, transitions and transformations)
If there's no such thing, example of good presentations or pointers on the subject would be appreciated.
Some times when the URL is clicked it navigates to the videopage, but I am hearing audio but not seeing any video. Why might this be?
I am using the latest version of Flash Player 10. The SWF in question was created in Flash 9 (CS2).
var s1 = new SWFObject("flvplayer.swf","single","560","400","7");

What is wrong with this?
Our app needs to know the sample count of the audio files it loads. The library we're using can reliably determine the sample rate, but not the sample count. Is it possible for us to calculate the sample count from just the file size and sample rate?
Hello everyone. I am working on a project that plays audio for part of the program. I would like to be able to display a message if the user's system volume is muted. I am using Python on Windows.
I would like to read the last 1 megabyte of a MP3 file and calculate SHA1 checksum for just that part of the file. The reason that I would want this is that when I'm looking for duplicate MP3's, the header info (song title, album etc.) can differ even though it's the exakt same audio file, so I figured I would be better of to checksum a part of the file at the end instead of the whole one. Is there an efficient way of doing this?
hi,
I have audio files in var/
This is the file name
2-3109999999-3246758493-1271129518-1271129505.6.wav
Format
2=campaign id
3109999999=caller id
3246758493=number called
1271129518=timestamp call ended
1271129505=timestamp call started
6=call id
If I were to pass just the number called which was 3246758493, how can I find all the files without defining all the other variables(such as timestamp, etc) and just the files that have that number in the filename?
Do you know any library in C# that I can use in order to read an existing *.mid file? I want to draw the sound frequency graph for the MIDI file, but I cannot get the inner data. I tried using NAudio and Alvas.Audio, but I wans't able to read a MIDI file. Any suggestions?

How to make VLC play .vlm config file in "With no interface mode" on windows?
So I have .vlm config file that should stream audio from mic to localhost so no vlc ui needed. If I say to windows "play .vlm file with vlc" it plays correctly starts server where I need and streams data. but how to do such thing manulay from cmd (so we suppouse we can call vlc.exe by vlc and we are now in folder with vlc.exe and vlcConfig.vlm file)
how can i create a checksum of only the media data without the tags to get a stable identification for a media file. preferably an cross platform approach with a library that has support for many formats. e.g. vlc, ffmpeg or mplayer.
(media files should be audio and video in common formats, images would be nice to have too)
Hi. Does anyone know a good C# tutorials (example) step by step?
It should be not a description of libraries, foundations and the OOP concept, and so forth, but the writing of any application step by step. For example, a mail client, telephone directory, a simple graphical editor, audio player.
Thanks!
For intance, text/html, audio/mpeg, etc? Can I safely assume that anything that is text based will actually have text/??? as its content type in the header when the server returns the document?

Are there good video tuts that show how to use this Object Alloc instrument to figure out if my objects and other stuff get freed from memory? Also, I have a bunch of C code and use Core Audio, so those are not really objects but still heavy in memory. Would like to know more about that Object Alloc instrument.

I'm trying to build a simple music player with a ListBox playlist. When adding audio files to the playlist, it first fills the ListBox with the filenames and then (on a separate thread) extracts the ID3 data and overwrites the filenames with the correct Artist - Title information (much like Winamp).
But while the ListBox is being updated, it's unscrollable, as it always jumps to the top on every item overwrite.
Any way to prevent this?
I'm a Linux user looking to write a program which will pick up the phone, dial a number, play a recording and record what the person on the other end of the line says and save it to an audio file. I will want to use the modem that came with my computer if possible. What should I use to write this program?
I'm planning on doing a application for Android 2.1 that changes song every minute (through what I hope exists in Android, "next") for the application using the audio device atm.
So if I have Spotify running in background already, playing music, can I through my program change to the next track?
Let me know if I was unclear about anything.
Thanks in advance!
I have a song and its lyrics. The song can be played using MusicPlayer class. But how do I show the lyrics of the song and also highlight them in sync with the audio. Words appear and fade with the playback.
Does Android have anything in-built for such a thing?
How can this be achieved?
Thanks.
Hi everyone,
I have an AVAudioSession under a AVAudioSessionCategoryPlayback category. I need to be able to stop or pause playback when the screen is locked. Is there any way to achieve this?
So far the only thing that produces an interruption to my audio session is an incoming call.
Thanks in advance!
