Hi, I am trying to implement the MPEG-2 layer-3 multichannel decoder, backward compatible with MPEG-1 layer-3. I am new to this work and I don't have any source code to implement this decoder, but I got spec 13818-3. Actually I am trying to build this multichannel decoder around the MPEG- 1 layer-3 and its low sampling frequency (lsf) stereo decoders like MPEG2, MPEG2.5. Main aim of th

Hi all, I have some codes for MPEG-4 AAC implementation. But they are floating point implementations. Is there any fixed point code available for MPEG-4 AAC for both encoder and decoder ?. If any of you have that code..plz forward to me. or send me the link to download. Regards, Ramya. __________________________________ Do you Yahoo!? Protect your identity with Yahoo! Mail AddressGua

Hi~ all I would like to implement MPEG Audio Layer II Decoder on 16 bit fixed point DSP. I've found the floating point C source code (dist.10) from univ. Hannover. But, It seems that it is not the final revision. (The encoder doesn't output the correct bitstream, maybe...) How can I get the final version of MPEG audio source code? Thanks in advance?? Min-seok

Dear List: I want to do some fast experiments with the MPEG Psychoacoustic Model - 2. Is there any source from where I can download the routines? I just need a simple program, where I give the input audio signal, and I get the masking threshold out. Any help in this regard will be highly appreciated, and also acknowledged.

Hello All, I need a favor. Can somebody tell me about the companies who are having MPEG-2/4 AAC decoder and among all of them who is having the best decoder? If somebody has already worked on AAC, may he/she share his/her experience about its performance, complexity, memory requirment, cycle count, no of channels supported by it for different profiles and some other related stuff which I

Hello, I am working on MPEG-2 AAC. I would like to know that how to decide value for Psychoacoustic entropy (PE) for block switching.I have ISO_13818-7_AAC stander but they do not clarify the value for PE for switching from long block to short block.Please if any one have idea about it, please help me............Thanks in advance.

Hi all, I am Mynampati Kuldeep Kumar. I am working on MPEG-2 AAC Low Delay Filter Bank. In this it has an algorithmic delay of 20 ms. The reason is as follows A forward and Inverse MDCT with N Frequency bands introduces a delay of 2*N-1 samples. By decomposing the MDCT into Windowing /TDAC and DCT (Type-4) it can be observed that DCT-4 generates N-1 Sample delay and Windowing/TDAC generate

Hi All, I am presently working on MPEG-4 HE-AAC. I faced problem with _twi(Twiddle)series,while i am doing the conformance testing. The vector is showing that its of AAC MAIN profile.But my decoder supports only AAC LC profile. So,is it necessary to test my decoder with _twi vectors? And also which series of vectors are sufficient to test Sbr part. If any one knows about this please mail
