Implementation audio compression techniques using embedded system

In this Paper study of various architecture for audio codec in an embedded system to demonstrate its effectiveness this is used to create completely self-contained digital audio encoder, based around a high-quality. General purpose audio compression algorithm The resulting audio encoder is able to operate 33% faster than the original Software only algorithm & hardware is able to achieve compression of 8KHz, mono, audio data in real-time.

Dynamic Range Compressors are a complex type of audio effect. The number of choices to be made during the design phase is vast. However, even using a compressor has its challenges, since the influences of the different parameters on the signal are not always obvious –especially to beginners. While properly setting up a compressor takes a lot of experience, a badly configured compressor can introduce a number of unpleasant artifacts’ to the sound.
