在八度/ matlab中从wavwrite转换为audiowrite的语法问题

Question

In Octave 3.8.1 I'm able to export a stereo wave file using the command below

wavwrite([w1(:) w2(:)],44100,16,'/tmp/testfile.wav');

I'm trying to get it to work with audiowrite using octave 4.0 see below but I get a audiowrite: wrong argument name error

audiowrite('/tmp/testfile2.wav',[w1(:) w2(:) w3(:) w4(:)],44100,16)

and

audiowrite('/tmp/testfile2.flac',[w1(:) w2(:) w3(:) w4(:)],44100,16)

It says audiowrite can have up to 256 channels am I incorrect about this?

Thanks

Try:

audiowrite('/tmp/testfile2.wav',[w1(:) w2(:) w3(:) w4(:)],44100,'BitsPerSample',16) 

or

audiowrite('/tmp/testfile2.wav',[w1(:) w2(:) w3(:) w4(:)],44100). 

16 Bits per sample is default. Check out the documentation here for more information.
