SoundInStartChart

SoundInStartChart [/Z] buffersize , destFIFOname

Starts audio data acquisition into the given FIFO.

Parameters

buffersize is the number of bytes to allocate for the interrupt time buffer which then feeds into the given Igor named FIFO destFIFOname. The FIFO must be set up with the correct number of channels and number type - use SoundInStatus to find legal values. The sample rate is read from the FIFO also, so that also needs to be correct.

Flags


/Z	Prevents errors from being fatal. V_flag is set to zero if no error, else nonzero if error.

Details

SoundInStartChart requires a computer with sound inputs. Several sample experiments using sound inputs are in your Igor Pro Folder in the Examples folder.

On systems where 32-bit floating point data is supported, you can use NewFIFOChan with no flags and a range of -1 to 1.
