Audio Compressor
Apply dynamic range compression with threshold, ratio, attack and release controls and export as WAV.
Feed-forward compressor: envelope follower (attack/release), classic over-threshold slope, then makeup gain. Peaks above the threshold are pulled down by up to the shown GR — great for taming vocal spikes before upload.
