Summary: SoX process using 100% CPU while converting ".qcp" file
Initial Comment:
The scenario is:
I am trying to convert "x.qcp" (EVRC type) file into "y.amr" file type as shown
below:
$./sox x.qcp y.amr
It has been observed that the CPU usage of Sox process has reached to 100%:
$ top
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
8006 adapter1 25 0 6892 1000 748 R 99.6 0.0 0:06.58 sox
The process becomes non responsive without throwing any error.
But If we repeat above test case with other ".qcp" file (QCELP 13K type) then
every thing seems to be working.
Just wanted to know is their any way out to handle EVRC type qcp file in Sox so
that its process should not got hang?
I manage to take gcore of that hang process:
<Code>

</Code>

Message:
Hi
SoX can't handle this type of file.
General
Complete name : Audio_142698AEFD7A05BC9BD36F4FD595CE9F.qcp
Format : QLCM
File size : 12.5 KiB
Audio
Format : EVRC
Bit rate : 13.0 Kbps
Channel(s) : 1 channel
Sampling rate : 8 000 Hz
Bit depth : 16 bits
New versions of FFmpeg will open it.
Can be used with SoX like this:-
$ ffmpeg -i "Audio_142698AEFD7A05BC9BD36F4FD595CE9F.qcp" -f sox - | sox -p
y.amr-nb
It isn't a SoX bug.
Somebody needs to close the report.
