I want to mix audio using SOX in linux. This is my script. I'm a total beginner on this thing.
time sox --buffer 128000 --combine mix audio1.mp3 audio_recorded.wav -C 64.0 "./Mixed.mp3"
time ffmpeg -loglevel warning -i ./Output.wav -c:a libfdk_aac -b:a 64k -map 0:0 -f segment -segment_time 10 -segment_list ./Output.m3u8 -segment_format aac './stream%03d.aac'
cd ..
but the result is like this..
sox FAIL formats: can't open input file `audio_recorded.wav': WAVE: RIFF header not found
real 0m0.003s
user 0m0.000s
sys 0m0.002s
The audio_recorded.wav
is a recorded audio file from android.
[REMOVED ANDROID CODE: no longer necessary]
UPDATE: I have tried to revise my recorder..set bit rate and sample rate same to audio1.mp3. Then I tried to mix it. This is now what happens:

I set the sample rate and bit rate of the recorded since when i tried mixing it in sox, it prompted me that the files dont have same channel and bit rate.
probably the file has no header. You can specify the file type with
-t <file-type>
this is the man page: http://sox.sourceforge.net/sox.html
