Subject: Adjusting write buffer for recording
Date: Fri, 9 Aug 2013 14:05:32 -0700	[thread overview]
Message-ID: <CACB3T6HYUWP+dAAQUdXNVR3uP78nZ=c5YQe-9XokZThL8-CSYw@mail.gmail.com> (raw)


[-- Attachment #1.1: Type: text/plain, Size: 838 bytes --]

Hello I have an application that processes audio as rec writes the file.

rec is buffering the data before it writes and I get the updates about 2 or
3 seconds late.

I have played with the --buffer pram and I not been able to see a
difference.

I would like to tell rec to write the data as soon as it gets it or reduce
the file write buffer size.

I have silence detection on

rec -c 1 -r 8000 --buffer 4096 currentRecording.wav silence 1 0.0001 2.1% 1
15.0 2.6%


The writes look like this

  Size of currentRecording.wav = 24576  Size of currentRecording.wav = 36864
*Size* *of* *currentRecording.wav* *=* *45056*  *Size* *of* *
currentRecording.wav* *=* *77824*


The data I am looking for is split between the two last writes ....


Any ideas ?

I just pulled down the source any ideas what file handles writing the files?


Thanks
