VoLIB TDU (DTMF+CP)

Stan Sidorov

Expert 1985 points

Hi there,

I am trying to make TDU identify three CP tones (dial tone, ringback and busy tone). Actually initial target is DTMF and CP detection together.

DTMF and CP detection works well but separately. However when I add dtmf between dial tone and ringback TDU cannot identify ringback properly. But other CP tones are detected without problems.

My audio tests are (8khz, 16-bit, u-law)

1. dialtone.pcm - fine

2. ringback.pcm - fine

3. busytone.pcm - fine

4. cp_full.pcm (dial, ringtone, busy) - fine

5. dtmf_cp.pcm (dial, dtmf, ringtone, busy) - ringtone is missed.

Question:

1. Is it possible to detect DTMF and CP tones with one TDU instance?

2. If so how to adjust TDU properly?

For test I am using TDU demo (Volib 2_1_0_1)

My settings:

tbool overwrite_scr; /* FALSE: Overwrite scratch buffers between calls */



tduSim.cfgCtl.u.cpt.startFreq = 300;
tduSim.cfgCtl.u.cpt.endFreq = 700;

tduControl (tduInst, tdu_CTL_CPT_ON, &tduSim.cfgCtl);

Stan,

Your question does not seem to be TI-RTOS related.

Are you using VoLib? On which device?

I am using DSP/BIOS on 5535 core. The question is for VoLIB performance. If there is another place to post this question please suggest it.

Thank you.

I have escalated your issue to a domain expert. But he may not be able to respond for a few days...

Can you send me the tone PCM examples you mentioned for us analysis?

Hi, Eric

Thank you for reply.

Here is a pcm file I am interested to detect. It is a sequence of dial-tone -> dtmf number -> ring-back ->busy tone. Actually I was unable to detect all events properly in this file.

16-bit, mono, Fs-8000Hz, u-law.

Hello Eric,

Did you try to detect CP events from the file? The topic is still relevant for me.

Thank you

With your file, I only have 10 digits detected. No other tones, let me know what is your observation.

So, any tones after 23 seconds (the last 3 tones) are not detected. My previous update was wrong.

What is your observation?

And one more interesting thing. I have another pcm file where all tones (events) are successfully detected. It consists of the same tones but their order is different (ringback ->dialtone-> busytone-> dtmf). There is a small fake detect, but the rest is fine.

Tone: CPT : Event: ON, Time: 140 ms, Power: -7 dBm0, Frame: 662

Tone: CPT : Event: OFF, Time: 0 ms, Power: -42 dBm0, Frame: 1038

Can you specify what is the platform? C55x, C64x+, C66x? COFF or ELF? Rel 2.1.0.1?

0 Stan Sidorov over 10 years ago in reply to lding

Expert 1985 points

For testing purposes I am using TMS320C5515EVM.
So it is:
CCS 5.5,

COFF,
volib_C55_2_1_0_1 CPU3

0 lding over 10 years ago in reply to Stan Sidorov

IN the previous test, I used C66x package. Then I tried C55x volib_C55_2_1_0_1 CPU3, I saw the same issue as you did. I will open a ticket and track it.

Stan,

I haven't get any update when this can be fixed yet. As you might know, the last VoLIB was released in 2013, it was not an actively developed project. So, the expectation is that there need some time for this to be resolved. Sorry for this!
