Hi all,
I'm trying to record by sox, splitting the input to multiple files:
$ sox --version
sox: SoX v14.4.1
$ rec -c 2 -b 16 -r 48000 -p trim 0 20 |
sox -V3 -c 2 -b 16 -r 48000 -p test.wav trim 0 10 : newfile : restart
I want to record 16-bit wav files, but the files generated are 32-bit ones.
$ soxi test*.wav
Input File : 'test001.wav'
Channels : 2
Sample Rate : 48000
Precision : 32-bit
Duration : 00:00:10.00 = 480000 samples ~ 750 CDDA sectors
File Size : 3.84M
Bit Rate : 3.07M
Sample Encoding: 32-bit Signed Integer PCM
Input File : 'test002.wav'
Channels : 2
Sample Rate : 48000
Precision : 32-bit
Duration : 00:00:10.00 = 480000 samples ~ 750 CDDA sectors
File Size : 3.84M
Bit Rate : 3.07M
Sample Encoding: 32-bit Signed Integer PCM
During recording, I have a message saying:
"rec WARN formats: sox can't encode to 16-bit"
When I record without splitting, I can get 16-bit wav files.
$ rec -c 2 -b 16 -r 48000 test.wav trim 0 20
$ soxi test.wav
Input File : 'test.wav'
Channels : 2
Sample Rate : 48000
Precision : 16-bit
Duration : 00:00:20.00 = 960000 samples ~ 1500 CDDA sectors
File Size : 3.84M
Bit Rate : 1.54M
Sample Encoding: 16-bit Signed Integer PCM
Is there any way to record 16-bit wav files, not 32-bit?
Regards,

Put the "-b 16" option immediately before the output file argument. You
can also drop all the format options preceding the -p since the pipe
format already includes all information.
That said, why don't you do the splitting directly with the rec command?
This should work:
$ rec -c 2 -b 16 -r 48000 test.wav trim 0 10 : newfile : restart

$ rec -c 2 -r 48000 -b 16 -p trim 0 20 | sox -p test.wav trim 0 10 : newfile : restart

Is the position of "-b 16" option okay?

I understand it, but I have to save test.wav first.
I just want to split into wav files while I record from the line input.

No, it needs to go immediately before the "test.wav" argument.

The command I suggested does exactly that.

$ rec -c 2 -r 48000 -p trim 0 20 | sox -p -b 16 test.wav trim 0 10 : newfile : restart
^^^^^
This was successful! I could record 16-bit wav files.

How can I stop recording? Can I set the recording time in advance?
