Five media: how they differ
| Medium | Frequency band | What you hear | Noise (100%) |
|---|---|---|---|
| Vinyl, 60s | 40 Hz – 11 kHz | Warm lows, a softer top, mono bass, rare clicks | −66 dBFS, clicks |
| Tape, 70s | 30 Hz – 14 kHz | A low-end bump around 90 Hz, tape saturation, light drift | −70 dBFS |
| Cassette, 80s | 60 Hz – 10 kHz | A dull top, audible hiss and drift | −58 dBFS |
| AM radio | 300 – 3400 Hz | Mono, no bass and no top, a dry transistor character | −52 dBFS |
| Lo-fi | 50 Hz – 7 kHz | 8-bit levels, a lower sample rate, strong drift | −50 dBFS |
The numbers are the preset settings at 100% amount: the band is where the lows and highs are cut, the noise is the average level of the added hiss. A lower amount means less noise and less colour.

Questions and answers
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.
What does Sound era do?
It moves a track into the sound of the chosen medium: it narrows the frequency band and adds saturation, speed drift and noise. Vinyl also gets mono bass and clicks, AM radio gets mono and a narrow band, and lo-fi gets 8-bit levels and a lower sample rate.
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.
Which files can I use?
WAV, MP3, FLAC or M4A, a file up to 100 MB. The full version takes tracks up to 10 minutes. The result is a WAV or an MP3 at 320 kbps.
Is the result different every time?
No. The noise and clicks follow a fixed rule, so the same track with the same settings gives the same file.
