Interesting solution! I'm surprised it can tell the diff between 6000 and 6001 hz, most audio devices run at fixed frequencies and most players don't bother correcting. Using your much-beloved sox utility on a fixed-rate raw file might give you more reliable and portable control -- resample it to one rate and force it to output at another rate.
:cool: after installing solaris 10 5/08/09 directory the computer rebooting then the massage "out of frequency" appear.i want a solution first

I'm trying to record audio using Audacity 2.0.5 installed from SlackBuilds. My system is 64-bit Slackware 14.1 and a sound card is Intel HD Audio. I didn't change my sound system to OSS. (Default sound system in Slackware 14.1 is ALSA, isn't it?) First, I set Internal Microphone slider in KMix... (2 Replies)
This is a small program as a tester for a basic sweep generator for bandwidth testing of AudioScope.sh.
This DEMO is only capable of 4KHz down to about 85Hz and back due to the low bit rate, but it is proof of concept for a much wider variant using a much higher bit rate.
The file generated... (4 Replies)

Hi all...
Well I have not been inactive but working out how to make OSX 10.14.x command line audio player have a variable sample rate.
This is a back door as afplay does not have a sample rate flag unlike aplay for ALSA, in Linux flavours.
This is a DEMO only but a derivative of it will... (2 Replies)
