How to use this workflow
Start with a short representative section
Choose a passage with vocals, rhythm and a gap at the end. A shorter source makes it easier to compare settings before processing the full recording.
Choose the rate first
Open Slowed + Reverb. Try Slowed Only to hear the rate change by itself, then adjust the rate. This tool links pitch to speed; 85% is its slowed preset starting point.
Add reverb and export
Enable reverb, choose a room and adjust decay and mix. Generate the effect, listen through the tail and download WAV or MP3 once the result works.
Make the pitch change an intentional choice
Slowing linked playback rate lowers the recording’s pitch. At 80%, a 440 Hz tone becomes 352 Hz and the source duration grows by a factor of 1.25 before reverb. This arithmetic explains the effect; it is not an included audio demo.
If you want slower music in its original key, use the independent speed control in the pitch changer instead. Add reverb afterward if needed. Those two workflows should not be described as identical.
Balance decay, pre-delay and wet mix
Decay sets how long the reflections persist; wet mix controls their contribution. Start with a low mix, listen through a lyric or chord change, and raise it only while the phrase remains clear.
Pre-delay separates the onset of the dry sound from the reverb. High cut darkens the reflection spectrum. The room choices are generated effect presets, not recordings of famous halls or analog hardware. Their names suggest a character rather than a measured venue.
Check the ending and the whole-file level
The generated file includes an effect tail, so it can last longer than source duration divided by rate. Listen past the final dry note. The renderer can lower gain when the combined effect would overload, so compare at similar listening levels.
Long slow versions need more processing memory. If the full file is rejected, shorten the input or reduce a long decay before retrying. Keep a WAV working copy when you plan more edits and make the MP3 delivery version after those edits are finished.
Common questions
Is there one correct slowed-reverb setting?
No. Tempo, arrangement and taste affect the result. The presets are starting settings, not verified optimum values for every song.
Where are the before-and-after example tracks?
This guide does not include demonstration audio. Load a recording you are allowed to use and compare its source and processed previews in the tool.
