Both limits apply. For longer recordings, choose MP3 or M4A; uncompressed WAV files reach the size limit sooner. Longer edits also need more device memory.

What does a slowed and reverb generator do?

A slowed reverb generator plays an existing recording more slowly and blends in reverberation: the lingering reflections you hear after a sound. Slowing playback lowers both tempo and pitch, while reverb makes the recording feel more spacious. It edits your recording; it does not compose a new song. Start at 0.85× speed with a 25% reverb mix and a 2-second tail. A 3-minute song becomes about 3 minutes 32 seconds before its tail. Compare the original and processed versions, then reduce the mix if the words or drums become blurred. Your source file stays unchanged.

Slowed + reverb preview

Snow On An Empty Street · 00:30–00:50

This 20-second excerpt comes from a public MemoTune song example. Each edit uses the same source and this tool, with a short fade at the cut points. The settings below include the added reverb tail.

Listen to the original vocals and drums, then compare the three edits. More reverb makes the tail more noticeable, but can blur lyrics and rhythm. These examples show one recording; the best settings depend on your source.

Shape the speed, space and final file

Make a slower version of a recording you already have. Set the pace, shape the reverb, then hear the complete edit before saving it.

Slow songs from 0.50× to 1.00×

Try a gentle 0.95× edit or take the speed down to half time. Pitch follows speed, so a 0.50× recording plays an octave lower and lasts twice as long.

Set the reverb mix and tail separately

Blend 0–70% reverb and choose a tail from 0.5 to 5 seconds. Start with less reverb on dense tracks; increase the tail when you want more space around sparse vocals or instruments.

Preview the audio you will export

Generate a complete 44.1 kHz WAV preview, including the final decay. Download that same file when it sounds right. Changing a setting clears the old result so you cannot accidentally export an outdated mix.

Listeners making personal edits

Work with up to 8 minutes of audio

Keep your recording on your device while you experiment. Choose one MP3, WAV or M4A file up to 30 MB and 8 minutes long; processing runs in this browser, so there is no audio upload or server queue.

A shorter path from your song to a slowed edit

Start with one recording and three sound controls. MemoTune keeps the processing and final file in your browser.

Free from the first edit

No account, subscription or credits are required to generate a preview and download its WAV.

Your recording stays local

Audio and filenames are not uploaded; tool interactions may be recorded as described in our privacy policy.

Three presets, room to adjust

Start at 0.85×, 0.95× or 0.70×, then set speed, reverb mix and tail independently.

Hear the file you save

Preview and download use the same 44.1 kHz, 16-bit WAV, including the reverb tail.

How to make slowed and reverb music in 3 steps

1. Choose your recording

Select or drop one MP3, WAV or M4A file up to 30 MB and 8 minutes long. Processing happens on your device, without uploading the recording.

2. Adjust and listen

Use the default slowed + reverb preset or change speed, mix and tail. Generate a preview, compare it with the original, and update the settings as needed.

3. Download your WAV

Save the finished preview as a 16-bit WAV. Keep the tab open until the download begins; refreshing the page clears your unsaved audio.

Find a slower mood for your recording

Work with your own music or recordings you have permission to edit. Slowing a track changes its timing and pitch; it does not grant permission to publish someone else’s music.

Songwriters exploring a demo

Try a slower version of your own demo to hear a different vocal register and pace. Compare it with the original before deciding which direction to take into your next session.

Video creators setting a mood

Give music you own or license more space for a reflective scene. Export the WAV and add it to your video editor, allowing for the longer running time and reverb tail.

Listeners making personal edits

Start with the gentle preset for a subtle change, or try extra slow for a lower, heavier sound. Keep the reverb light when you want the words and drums to stay distinct.

The recording plays more slowly, its pitch drops, and reverb adds a decaying sense of space. The lyrics, instruments and song structure come from your original file. This is an audio effect rather than an AI cover or a newly composed track.

Start at 0.85× speed, 25% mix and a 2-second tail, which are the default settings here. Listen to a vocal phrase and a busy drum section. If words become hard to follow, lower the mix; if the edit feels too heavy, move the speed closer to 1.00×.

This tool changes speed and pitch together. It does not offer pitch-preserving time stretching. At 0.50× speed the recording is one octave lower; at 1.00× the original tempo and pitch remain, so you can add reverb alone.

Choose MP3, WAV or M4A files up to 30 MB, 8 minutes and 2 channels. The codec inside the file must be supported by your browser; protected or unusual files may fail. Downloads are 44.1 kHz, 16-bit WAV only. WAV can be larger than the source MP3 and does not restore quality already lost to compression.

The tool is free and requires no login, subscription or credits. Audio processing takes place in this browser, and audio bytes and filenames are not sent to MemoTune. Tool interactions may be recorded for analytics as described in our privacy policy. Refreshing or closing the page discards unsaved audio.

Decoded audio uses more memory than a compressed file, and slowing it down makes the result longer. A phone may run out of memory even when a file meets the size limit. Try a shorter recording, close other tabs, or use a desktop browser. The original file on your device is unchanged.

Only if you have the necessary rights to the original recording and composition. Slowing a song or adding reverb does not remove copyright or grant a commercial license. This tool changes the sound, not the ownership or platform rules that apply to it.
