Subject: The perennial question of controlling the volume of sound cards through Matlab ... From: Stuart Rosen <s.rosen@xxxxxxxx> Date: Thu, 10 May 2012 10:32:24 +0100 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY><html> <head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> </head> <body bgcolor="#FFFFFF" text="#000000"> Until recently, I have been happily using the software provided by Trevor Agus to control sound card volumes through Matlab in Windows 7.<br> <br> We now are using an RME Babyface, which has a similar mixer control to the other Fireface boxes (RME TotalMix FX). We have been able to control one of the volume settings (the local one) using the previous means in Matlab, but we cannot seem to get access to the main volume control (which overrides all the others). <br> <br> I'd be grateful to know if anyone has faced this problem and come up with a solution.<br> <br> Yours - Stuart<br> -- <br> <div class="moz-signature"> <hr> Stuart Rosen, PhD<br> Professor of Speech and Hearing Science<br> UCL Speech, Hearing and Phonetic Sciences<br> 2 Wakefield Street<br> London WC1N 1PF, England<br> <br> Telephone numbers: <ul> <li>Office: (+ 44 [0]20) 7679 4077</li> <li>Admin: (+ 44 [0]20) 7679 4050</li> <li>Internal: ext 24077</li> <li>Fax: (+ 44 [0]20) 7679 4238</li> </ul> Email: <a class="moz-txt-link-abbreviated" href="mailto:stuart@xxxxxxxx">stuart@xxxxxxxx</a><br> Home page: <a class="moz-txt-link-freetext" href="http://www.phon.ucl.ac.uk/home/stuart">http://www.phon.ucl.ac.uk/home/stuart</a><br> <br> Request an inspection copy of <i>Signals and Systems for Speech and Hearing, 2nd edition</i> by Stuart Rosen & Peter Howell<br> <a class="moz-txt-link-freetext" href="http://info.emeraldinsight.com/promo/signals.htm">http://info.emeraldinsight.com/promo/signals.htm</a><br> <hr> </div> </body> </html>
