Hi, I am building a sound editor and I wrote code to extract samples from the wav files. I would also like to support processing of mp3 files in my application. Instead of using a library to parse the mp3 files, I am planning to convert the mp3 files to wav files (from within my program) and then perform the wav processing functions that I have already written. Is there a software I can use to convert mp3 files to wav files from within my program? Thanks, Vandana.

[linux-audio-dev] hammerfall 9652

by Thomas Vander Stichele

Hi, still trying to record sound from my hammerfall cards' s/pdif input. I started writing a howto detailing what I'm going through, because i haven't found much info on the hammerfall while googling. I figured it would be wise to make sure I understand all output that ALSA gives me first. Unfortunately a lot of what I need is not documented outside of code. So, maybe some people here can help me. Here's some output from /proc/asound, along with questions: [root@framboos root]# cat /proc/asound/card0/rme9652 RME Digi9636 (Rev 1.5) (Card #1) Buffers: capture cdc00000 playback cda00000 IRQ: 5 Registers bus: 0xde000000 VM: 0xd0894000 Control register: 24104c Latency: 4096 samples (2 periods of 16384 bytes) --> should I be increasing this latency ? Hardware pointer (frames): 0 Passthru: no --> what does Passthru mean in this context ? Clock mode: autosync Pref. sync source: ADAT1 --> I guess this means it tries to get some sort of sync signal from ADAT1 input port ? ADAT1 Input source: ADAT1 optical --> This seems to indicate my ADAT1 input is set up for taking S/PDIF ? IEC958 input: ADAT1 IEC958 output: Coaxial & ADAT1 --> If I set this to output to optical, can I then take the S/PDIF input on ADAT1/IN passed through to ADAT1/OUT ? IEC958 quality: Consumer --> How do I set this to Professional ? I'm recording from our AMEK digital mixing desk and it sends out Professional. I didn't find any option in asound.state for it. IEC958 emphasis: off IEC958 Dolby: off IEC958 sample rate: 48000 ADAT Sample rate: 48000Hz ADAT1: No Lock ADAT2: No Lock ADAT3: No Lock --> This looks like it gives the current status of the input channels; ie, they would indicate "Lock" if they were receiving a valid signal, correct ? Timecode signal: no Punch Status: 1: off 2: off 3: off 4: off 5: off 6: off 7: off 8: off 9: off 10: off 11: off 12: off 13: off 14: off 15: off 16: off 17: off 18: off --> What does Punch Status mean ? I appreciate your time in answering these questions if you do and I hope to put together a useful s/pdif hammerfall recording howto based on it.

[linux-audio-dev] LAD conference Karlsruhe info

by Frank Neumann

Hi list, the Linux Audio Developer's Conference in Karlsruhe is soon to begin, and here is just a little information I wanted to give you: - The live audio stream to be broadcast on Friday and Thursday (probably between ~ 2 P.M. and 9 P.M. on both days) is available at these LiveIce servers: x http://plugin.org.uk:2300/liveice (currently set to max. 50 clients) x http://politik.uni-duisburg.de:2300/liveice (max. 20 clients) We have never done this before, so forgive us if we run into problems there. - In order to have a "channel back" from the audience, some of us might lurk on what I think is the inofficial IRC meeting point, irc.openprojects.net, channel #lad. See also http://www.linuxdj.com/audio/lad/irc.php3. - Photos will be made, for sure :-). I don't know yet when and how we can make these available; probably already during the conference, time permitting. - The same is true for recordings of both the talks and the music we (might?) make. These might take a while to be made available. Greetings, Frank PS: Oh, and yes, reports..right. Some time later, hopefully :-).
