Looking at your post, You are already using the best format.<br>If you do not have a fast filesystem try making a ram disk and play the files from there instead.<br><br>if you *really* want you can use sox to turn them all into raw alaw files and rename them with a .PCMA extension<br>
to avoid the g711 transconding but g711 to PCM is pretty trivial. it&#39;s more likely a file i/o distress you see.<br><br><br><div class="gmail_quote">On Thu, Apr 16, 2009 at 5:04 PM, Nik Middleton <span dir="ltr">&lt;<a href="mailto:nik.middleton@noblesolutions.co.uk">nik.middleton@noblesolutions.co.uk</a>&gt;</span> wrote:<br>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I’m looking for the optimum audio format when using
streamfile in a lua script.</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I’ve found CPU load increases rapidly with the number
of threads playing a .wav file.  Can anyone tell me the optimum when using
g711a?</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Right now the the .wav files are </span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Audio format: PCM</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Sample rate : 8 kHz</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Mono</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Sample Size: 16 bit</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Bit rate           :128kbps</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Will it help CPU load if I resample to a bit rate of 64kbps
and sample size of 8 bit?</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">I have read that the sample size needs to be 13-14bit  +1
for alaw/ulaw though</span></font></p>
