Pre-emphasis on the stereo bus

Introduce a gentle high-shelf at 12 kHz before limiting. This compensates for typical MP3 psychoacoustic roll-off without sounding brittle.

Embed ISRC codes, contact details, and artwork. CompressMP3 preserves ID3 tags so your recipients never lose critical context.

Always keep a 24-bit WAV master. Use CompressMP3 to generate the promo MP3 when you need it, ensuring future-proof conversions as algorithms evolve.
