What changes in the sound
- Only 300–3400 Hz. What remains is the band of speech: there is no bass and no top at all.
- Mono. The left and right channels are summed into one; the noise is mono too.
- Transistor saturation. Half of the signal goes through saturation, so the sound gets dry and dense.
- On-air noise at about −52 dBFS, in the same narrow band as the music.
- No speed drift. Radio does not wobble like tape, so tempo and pitch stay steady.
When the AM radio sound works
For intros and outros, transitions between parts of a track, a voice “from the radio” in a verse or a skit at the start of an album. Over a whole song the effect is too strong, so it is usually used for a section.
Tip: make the full version, cut the part you need in the audio cutter and drop it into your project.

What to do next
Questions and answers
Why is the bass gone?
That is how AM radio sounds: it carries only the mids, about 300–3400 Hz. If you want a retro sound with bass, choose vinyl or tape.
Can I process just the vocal?
Yes, if you have a separate vocal track. If not, split the vocal off with the vocal remover, process it here and mix it back in.
Is it free?
Previewing the first 25 s is free and needs no sign-in; free previews per day: 20. The full version costs 1 token per file and needs a sign-in.
Can I make the effect lighter?
Yes. The Amount slider blends the processing with the original from 0 to 100% in 5% steps. At 30–50% you keep a light touch of the medium; at 100% you get the full preset.
Should I master it afterwards?
If the version goes to streaming platforms, yes. The preset does not even out loudness; it only keeps peaks under 0 dBFS. Mastering brings the loudness to the platform's target and keeps the era's character.
