ADPCM decoder required

Started by Sanjam November 2, 2006
Hi all.
I am recording voice using ML2390 codec. It records speech in the ADPCM
format. Now I wish to listen to the recorded data to validate whatever
I have recorded. I need an ADPCM decoder for that. I tried out
downloading numerous ADPCM players and decoders from the net but none
proved to be useful. Can anyone come up with some solid solution for the
same.?
How can I use G.726 standard in this regard?
Regards
Sanjam

What's wrong with the ones you found on the net? Did you also look for
G.726 players?

Depending on the player, you may need to store your data in .wav format
and set the correct "compression type" parameter in the .wav header.

G.726 includes 16, 24, 32, and 48 kbps ADPCM rates. What is the bitrate
of your ADPCM data?

I have never heard of a ML2390 codec, but by definition a codec is a
coder/decoder, so you should already have the decoder.

Yes, there are MANY types of incompatible ADPCM codecs. You should be
able to get the decoder from the same source as the encoder.

I have no idea. Is your ML2390 codec supposed to be compatible with G.726?
