SOUND PROCESSING:
1. In
sound processing application, Music compression(MP3) is achieved by converting
the time domain signal to the frequency domain then removing frequencies which
are no audible.
2. The
time domain waveform is transformed to the frequency domain using a filter
bank. The strength of each frequency band is analyzed and quantized based on
how much effect they have on the perceived decompressed signal.
3. The
DSP processor is also used in digital video disk (DVD) which uses MPEG-2
compression, Web video content application like Intel Indeo, real audio.
4. Sound
synthesis and manipulation, filtering, distortion, stretching effects are also
done by DSP processor. ADC and DAC are used in signal generation and recording.
