02 Oct 2003	Trent Mankelow	This is simply the best piece of software ever written.
28 Nov 2003	Huss Habiboglu	Very neat and nice indeed! I think you're using PortAudio. Thanks!
21 May 2004	Ryu Araki	very nice, but with 'async' mode support, this package will be more and more useful. Regarding 'async' mode, see "help wavplay";-)
22 May 2004	Artur Ready	Excellent job. Its very helpfull. :)

28 Dec 2004	Christopher Brown	ASIO works great with the Echo Gina3G multichannel card. Thank you!
02 Mar 2005	Ipek Oruc	Works great! Very useful!
11 Mar 2005	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.
05 Apr 2005	Thomas S	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)! :(
06 Apr 2005	David Hallett	Once again Matt Frear amazes us with his amazing talents and produces software that exceeds even our most lofty expectations. Well done Matt!
09 Dec 2005	Ray Goldsworthy	I would love some follow up concerning using this file with the MBox since that was the only negative review. grazi: raygold@mit.edu
30 Jan 2006	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
23 Feb 2006	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
23 Mar 2006	Philippe-Aubert Gauthier	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!
06 Apr 2006	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?
16 May 2007	Erik Östlin	Fantastic; it worked straight away with my Digigram VXPocket 440 soundcard (4 outputs and 2 inputs); many thanks!
28 Jan 2008	V M	Worked extremely well out of the box! Why hasn't something like this been incorporated into Matlab yet?
15 May 2008	oktus oktus	Works well with my Creative E-MU 0202 USB SoundCard
