Synthesizer: The Functions of Filter (4)

 

 

3. Means for adjusting balance between partial frequencies

 



- If there is any wave sampled from 'C' and 'D', there will be deviations depending on the actual partial frequency of this wave, and the playback range is enlarged and the sound will be severely distorted.

- For easier understanding, suppose the spectrum of the original sound before sampling.

- Let me assume that 'C' was distorted more than the original note with more bass sounds. This  distorted bass can be reduced to the original sound by adjusting the passage of the bass sounds  with the High-Pass Filter. All of these distortions come from the distortion of the sample, and the distortion rate increases as the playback range widens.

- This phenomenon is different from actual sound by expanding the sampled sound in proportion only according to the keyboard scale.

- This scaling is natural in terms of the pitch, but it is a problem that the scaled sound is different from the actual musical instrument sound.

- There can be many cases depending on what spectrum the actual sound is made of, but like 'C', the 'D' sound is produced by proportional scaling, resulting in distortion of the amplitude compared to the real sound.

- This distortion can be eliminated by removing the distortion through the Low-Pass Filter; that is, by reducing the amount of passage in the high-pitched portion, it ('D') can be similar to the original spectrum.
