Record sound?

[alex]

Anyone know how to record a sound from the microphone input to either a wav
file or directly into an array?

I would prefer not to use MCI (as it is old and unpredictable from one PC to
another).

Hi Alex,

Please find attached a sample of a vi which will do this - it records a snapshot of sound from the mixer (you can specify how long and at what sample rate), displays it on a waveform graph and replays it through the mixer.

It is currently saved for LabVIEW 8 - please let me know if you need another version, or have further questions.

Many thanks,

Since we are on the LabWindows/CVI board, how about a CVI version?

Hello Mark,

Could you post this file saved for Labview 7.1?

Thanks,

Hi Celso,

I should really post this on the LabVIEW forum, but am having problems posting on there at the moment!

I've re-written the sound recorder in LV 7.1 for you, this version records a set amount (in seconds) of audio from the soundcard, displays both channels on a waveform graph and writes the data to a .csv file. The file writer vis can be substituted with vis to write the sound to a waveform file as required.

I hope this helps!

Mark
