processing problem

Post by stebod » Thu Jul 27, 2017 6:20 am

I had everything working fine and then today when i run my sketch i get
==== JavaSound Minim Error ====
==== Couldn't open the line: line with format PCM_SIGNED 200000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian not supported.
any ideas ?

IS that 200 kHz sample rate ?
The upper sample rate is 96 kHz.

hI Matt, in the sketch code its is
int buffer_size = 4096;
float sample_rate = 200000;

As i said this did work just fine until yesterday and now i just get

==== JavaSound Minim Error ====
==== Couldn't open the line: line with format PCM_SIGNED 200000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian not supported.

Whatever i change the sample rate too i just get the same error, its an FFT sketch for a spectrum analyzer. I did have it running on the pi and audioinjector as seen here

I seem to have sorted this problem by installing pulseaudio, no idea how or why but the processing sketch works now
