Hi all,
I'm converting a file called vocals.wav to vocals.mp3
vocals.wav
<https://drive.google.com/file/d/1he1eCJag1G8iGkgL932jy_mXuLT_khGM/view?usp=drive_web>
For this I'm using this command
```
sox vocals.wav vocals.mp3
```
and here is the result of the corresponding files
- original file
```
soxi /Users/martin/Downloads/split-test/vocals.wav
Input File : '/Users/martin/Downloads/split-test/vocals.wav'
Channels : 2
Sample Rate : 44100
Precision : 16-bit
Duration : 00:03:00.00 = 7938000 samples = 13500 CDDA sectors
File Size : 31.8M
Bit Rate : 1.41M
Sample Encoding: 16-bit Signed Integer PCM
```
- converted file
```
soxi /Users/martin/Downloads/split-test/vocals.mp3
Input File : '/Users/martin/Downloads/split-test/vocals.mp3'
Channels : 2
Sample Rate : 44100
Precision : 16-bit
Duration : 00:03:00.04 = 7939544 samples = 13502.6 CDDA sectors
File Size : 2.88M
Bit Rate : 128k
Sample Encoding: MPEG audio (layer I, II or III)
```
You can see that the duration is not the same which is weird and the number
of samples also changed.
In fact, 1544 samples have been added to the beginning of the file
If I try to launch `sox -V vocals.mp3 vocals-trimmed.mp3 trim 1544s` it
does not work
Can you please help me
Thanks
