Equalize/match volume of different bits in one channel?

Post by MrAnalogy »

I've got a recording of two people talking. All in one channel. One speaker is much louder.

Is there a way to normalize all the sections to roughly the same loudness (volume)?

The waveform looks fine to me...

You can use the Compressor/Expander effect with the Reduce Peaks preset.

Dynamic Compression makes the loud parts quieter and/or the quiet parts louder. Limiting is a kind of fast compression that "pushes down" the peaks. Compression and limiting is one of the most commonly used effects in audio production (along with equalization and reverb). Almost every professional recording has some compression.

Mostly compression and limiting are used to reduce the loud parts/peaks and then "make-up gain" is used to bring-up the overall loudness.

IMO - Many modern recordings are over-compressed to "win" The Loudness War and the constant-loudness makes the music boring.

Expansion is the opposite and it makes loud parts louder and/or quiet parts quieter. It's rarely used except for noise-gating. A noise gate is a downward-expander that makes the quiet parts quieter or kills the quiet parts completely.

(GoldWave sometimes gets compression and expansion mixed-up but the presets names/descriptions are correct and that should keep you on the right track.)
