Sound conecpts

[gautamzone]

Hi friends,

I would just like to know some sound concepts like
1. WaveTable Synthesis
2. FM Synthesis
3. MPU 401
If there are any links to describe these concepts, I would be very grateful if you could share them. Also, any idea from your side on these concepts would be appreciated.

Thanks a lot

Gautam

wave table synthesis Last modified: July 8, 1997



A technique for generating sounds from digital signals. Wave table synthesis stores digital samples of sound from various instruments, which can then be combined, edited, and enhanced to reproduce sound defined by a digital input signal. Wave table synthesis reproduces the sound of musical instruments better than Frequency Modulation (FM) synthesis.

The MIDI standard supports a wave table format. Not all sound cards, however, support wave table synthesis.

FM synthesis
frequency modulation synthesis
There are two main ways to synthesize music: frequency modulation, and sampling from a wavetable. FM synthesis uses a signal to modulate the frequency of another signal, and the results sound like arcade games from the 1970s or one of the first wave of poker-faced European techno-bands. Each FM voice needs at least two signal generators (or operators), and the more sophisticated FM systems may use four or six operators per voice. In general, however, FM synthesis is not as desirable an asset in your sound circuitry as wavetable synthesis.

Thanks a lot for your response morriswindgate.
It was very informative.
