The compressor threshold is the level point in db above which the audio gain will be reduced...

P501 audio processor user manual page 8 the release time is how quickly the compression effect is removed when the audio falls back below the threshold. The p501’s release time is programmed to follow the dynamics of the falling audio level. This is an important aspect of the p501’s compressor desig...

P501 audio processor user manual page 9 notice that the pure tone audio signal is beginning to lose its smooth top and bottom curves and begins to resemble a triangular waveform. This is not just an issue for bass guitar and bass drum compression. Many audio sources including piano and vocals have e...

It is often difficult to achieve the attack speed without the undesirable over compression. The peakride compressor achieves this by altering the ratio of the compressor...
