Improving the sound
Can I use EQ and compression?
Yes — an equaliser, compressor, reverb and de-esser can be added per lane, under the Advanced disclosure in the lane inspector. A clip carries only Enhance voice: the rack lives on the lane.

They sit behind Advanced on purpose: most episodes need "make this voice sound better", which is a preset, not a parametric EQ. Reach for these when you know exactly what you want to change.
For a recording with real problems — noise, uneven level — the Noise Remover and Speech Enhancer will get you further than an EQ will.
