Fade out perception

The fade out trick

You have probably stumbled upon the difficult task of a simple fade out (or in) in mastering (and/or mixing). It sounds as if there are high- and a low-pass filters that are slowly closing the frequency spectrum. This got me thinking of other ways to improve the flaws of the fade.

Our perception of sound pressure is different over the frequency spectrum and it differs depending on sound pressure.

Frequency spectrum of bit reduction, dithering and noise shaping

The difference between 16-bit depth and 24-bit depth audio

This is an audio (and visual) visualization of three different bit reduction conversions from 24bit to 16bit audio. With / without dither and noise shaping.

The LANDR eq algorithm

I did some in depth research and testing of the EQ algorithm with the LANDR website and some sinus tones. The tests are made with mp3 quality files but I still believe you can do a relevant reading out of the result, the most relevant reading being the handling of peaks.

TK-audio, BC2-ME mastering compressor

Every mastering facility needs a great stereo/bus compressor with that nice smoothing effect to use as glue for the sound. This compressor is a further development of the G-series compressor made famous by the SSL (solid state logic) company.
