audio driver

Hi all, I need to know the process of configuring and using an audio codec for capturing and playback of live audio in an 8051 platform board. I need pointers to detailed guide ( other than datasheets) for using codecs. I tried google but results were mostly related to some operating systems or FPGAs. Thanks in advance. Romesh.

There are many different 8051 systems. If you use a 1 MHz system, software codecs like Ogg Vorbis might be not possible. PCM should be possible all the time, but this limits the length of the audio you can record. So in order to help you, you should answer the following questions:

- how fast is your system?

- how much memory do you have?

- do you want to save it permanently, maybe sd-card or flash?

- what quality do you need? (8 bit, 16 bit, sampling rate?)

Based on the answers of this questions, you can select the right codec.

There are hardware codecs, too, which allows better compression, even with slow 8051 systems. If you are too lazy to read the datasheet and implement the code to configure such codecs, there are many people (including me) in this newsgroup who can do this for you for their standard hourly wage.
