pa-wavplay

Play and record multi-channel audio using either an ASIO, DirectSound, or Windows multimedia audio d

Description

The zip file contains 3 separate MEX file dlls, one for asio, one for windows audio, and one for directx.

See the included pa_wavplay.m, pa_wavrecord.m, and pa_wavplayrecord.m for documentation.

pa_wavplay uses the open source portaudio API.

• MATLAB release: MATLAB 6.5 (R13)
• Other requirements: Win32 only. Source code available at: http://sourceforge.net/projects/pa-wavplay/

This is simply the best piece of software ever written.

[Huss Habiboglu]

Very neat and nice indeed! I think you're using PortAudio. Thanks!

[Ryu Araki]

very nice, but with 'async' mode support, this package will be more and more useful. Regarding 'async' mode, see "help wavplay";-)

[Artur Ready]

Excellent job. Its very helpfull. :)

ASIO works great with the Echo Gina3G multichannel card. Thank you!

[Ipek Oruc]

Works great! Very useful!

[Daniel Oberfeld]

Great, exactly what I was looking for... Tried to code something myself with PortAudio, but this tool saved me loads of time.

Two comments:
1) Would be nice if one could control the latency between input and output. I use an RME Digi 9636 and the recodings always have some 100 ms of silence at the beginning.

2) Sometimes I get 'truncated playback': the last few ms of a sound are not played. I use a simple workaround by padding the sound with 100 ms digital 0.

I can't seem to get any sound in or out using M-box (I've installed the ASIO core drivers available on Digidesigns homepage)! :(

Once again Matt Frear amazes us with his amazing talents and produces software that exceeds even our most lofty expectations. Well done Matt!

I would love some follow up concerning using this file with the MBox since that was the only negative review. grazi: [e-mail]

[Bob Setseo]

First of all how do I get this application to run.I am new to matlab so please would someone give me a step by step guide on how to do this.I want to play a wav file that has 5 columns in matlab so i understand pa_wavplay can do that.However,I realised the setup is quite straight.What other supporting libraries do i need to download and where do i install what.do the dll's go into my matlab working directory or somewhere else?

Too many questions,please help

[Peyroutet Olivier]

Very good software, but I've got a mistake with memory management: I have put the function call 'pawavplayw' into a loop to continuously record 1 second samples, but it uses more and more memory, and Matlab crashes after about 50 iterations.
So do anyone have the solution to this problem?? (how to release memory between each iteration?)
thanks

A really great set of functions. I am now using pawavplaya directly and wondering why (by comparison with "soundsc" or "sound" in Matlab) it is not possible to make something else (in the command window) when "pawavplaya" is running ... "sound" seems to be based on "playsnd" which does not stop the access to the command window. Anyway, the functions are so great that I must admit that without that I would not have been able to finish my PhD on time!

[Philippe-Aubert Gauthier]

I am wondering if pa_wavplay is working with ASIO or ASIO2? Since it is from 2003, and I think (?) that ASIO2 are from 2002-2003?

[Erik Östlin]

Fantastic; it worked straight away with my Digigram VXPocket 440 soundcard (4 outputs and 2 inputs); many thanks!

[V M]

Worked extremely well out of the box! Why hasn't something like this been incorporated into Matlab yet?

[oktus oktus]

Works well with my Creative E-MU 0202 USB SoundCard

Anybody heard about a a win64 compiled version of the pa_wavplay's sll?

[Philippe-Aubert Gauthier]

Following my previous comment, here is my recent advice. On win64 bits, I have not been able to run pa_wavplay in Matlab 64 bits. Using Matlab 32 bits in Win 7 64 bits, I have been able to run pa_wavplay without any problem with a 96-channel system made from MOTU sound cards.

[Rafal Samborski]

Good job! Works well with Lexicon Ionix u82s ASIO.

[Trevor Agus]

Really useful code, thanks. Is there (or could there be) an option to suppress the text output that seems to be standard. Whenever I play a sound using pa_wavplay, I get output such as:

Using ASIO driver
Playing on device 0

This can be reassuring, but it is problematic if (say) you're trying to test whether someone can hear the sound or not.

[Corey Gravelle]

Pretty good stuff, my only gripes would be my inability to turn off the printed text "Playing on device (x)" and "Recording on device (x)", probably because I'm a DLL novice. Also, the lag between recordings (see Daniel Oberfeld's comment) was an issue for my planned use. Nevertheless, great coding and thanks!

[Kenneth Faller II]

Does this support synchronous or asynchronous audio IO?

[Ajay Kumar]

What is is the maximum number of channels that it can support?
I plan to use about 64 Inputs. I can manage to find a 64 Input sound card. But, is it possible to record all those channels using this code?

[Li Shenguang]

Great!It's just what I am looking for~~~
