Any software that can analyze recorded audio file and extract CTCS/DCS/whatever codes

[4L4AGU]

Say I have a recorded audio file, where a lot of operators talk, each one uses personal tone signaling code, to show others which one is talking. So is there a software, which will analyze recording and extract "callsigns" of all participating sides?

Phone Tone Decoder does that. And I am sure others are available that use the computer sound card.

That is if you are talking DTMF. A sound card frequency counter that has a lowpass filter can get CTCSS codes, If your recorder records sub audible.

I'm talking about the chirps that sound like old times modem sound. Have no idea about how it is called.

What band and mode are you operating ?

VHF/UHF. I'll try to record and upload a sample.

This may be something that will work for you.

Good luck.

It sounds to me like he's listening to a commercial repeater, which probably uses a packet modem to identify each user. That packet data would either be decoded by the repeater for re-transmission to specific stations, or it might just be repeated back out to open squelch on specific receivers.

Either way, that's neither DCS nor CTCSS, and without more knowledge about the system you're talking about, I couldn't give much in the way of advice.

Sounds to me like you are describing MDC1200. That would sound like a short burst of data as a preamble or postamble to the voice transmission.
Try using this to decode it http://www.antistatic.org/winmdcd/
