I use the following code to trim, pipe and concatenate my audio files.
sox "|sox audio.wav -p trim 0.000 =15.000" "|sox audio.wav -p trim 15.000" concatenated.wav
One would expect that concatenated.wav
will sound identical compared to a.wav
.
However, when both files are played simultaneously together, there is a distinct audio shift on concatenated.wav
.
Normally this error is acceptable as it is in the milliseconds range. However, as the number of pipe increases (say more than 100), the amount of audio shift increases substantially.
What is the correct method to trim, pipe and concatenate audio files using SoX to prevent this error?
Edit 1: Samples was used instead of milliseconds. Still met the same problem.
The following code was used:
sox "|sox audio.wav -p trim 0s =661500s" "|sox audio.wav -p trim 661500s" concatenated.wav
Wave file sample rate is 44100hz
. Sample size is 16 bit
.
SoX 14-4-2
was used.
