Other Parts Discussed in Thread: DM3730, OMAP3530
we r usingDM3730 evm running on wince 6.0 ,the DVSDK provided for this board has source code for an application using G.711 codec which runs on DSP part of DM3730, as mentioned in DVSDK user guide
for encoding and decoding the speech data,the input for the encoder is recorded speech file(.wav),the encoder generates a output file using G.711 compression,this output file is fed to the decoder exe to get back the original speech signal,the decoder generates uncompressed speech file(.pcm).
we r using the below commandline commands:
1.speech_encode_io1_omap3530 -c g711enc -i davincieffect.pcm -o davincieffect.g711 --compandinglaw alaw -n 1000
2.speech_decode_io1_omap3530 -c g711dec -i davincieffect.g711 -o davincieffect.pcm --compandinglaw alaw -n 1000
WE R ABLE TO GET EXPECTED RESULTS FROM THE ABOVE PROCEDURE.... but we need to modify the above applications to take dynamic speech input data from microphone rather than a recorded speech file(.wav). how can we do this ????????
thank u
