问题描述:

I am trying to convert a PCAP containing a RTP Payload with an octet-aligned AMR-WB payload to a playable AMR file.

Regarding the AMR storage format described in http://tools.ietf.org/html/rfc4867#section-4 between SID frames NO_DATA (0x7C) frames need to be inserted.

This is especially important when using DTX (discontinuous transmission) mode.

The question in AMR Raw Output from Wireshark not playing in players describes a way to convert a single PCAP UDP packet to AMR but does not consider a whole packet flow where packets need to be concatenated or NO_DATA frames need to be inserted after SID frames in DTX mode.

I managed converting it parsing every packet with PCAP.net and now wonder whether my output is correct. I could not find any information on which audio player supports AMR-WB in DTX Mode, though.

VLC Player plays it correctly with the speech pauses, but shows the wrong total time of the file and when converting it to *.wav (using VLC), there will be no speech pauses anymore.

I would like to analyze my speech data using a tool as audacity which shows the spectrum of the sound. Unfortunately, audacity shows loud bangs in the speech pauses (see picture). Therefore, I do not know whether audacity just does not support DTX or my output is corrupt?

It would be great if you can help.

Here the output Soundfile (just use a hex editor and call it *.amr):
