Hi, I have used helix mp3 decoder before, for my new project I have this limitation that I have a 200Kbits total bandwidth for my network, I have a cortex M4 with a 100MHz clock, so I want to know if there are some open source C library’s that would decode and encode the audio, so it can be done both the decode and encode the audio with 16bit’s data and at least 20K samples per second Realtime with the M4. So, the audio would be small enough to pass the network bandwidth, the MP3 decoder source is available, the problem with it is the encoder is not available as open source also it uses lots of CPU cycles to encode and decode at the same time, and it’s an over compression for this project. Any ideas are welcome!
