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

Works well with my Creative E-MU 0202 USB SoundCard

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

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

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?

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!

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

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

I would love some follow up concerning using this file with the MBox since that was the only negative review. grazi: raygold@mit.edu

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)! :(

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.

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

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

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