What you see is what you hear

Navigate through the audio track intuitively with the help of the overview waveform and the zoomable detail view. Lotsa keyboard shortcuts gives you full control and helps to focus on your instrument.


Multiple Loops

Create and store as many loops as you need. All loop markers are saved with the song and are available next time you open the song.


Tone & Pitch Filter

Emphasize the instrument you want to hear while suppresssing others with the easy-to-use filter sliders.


Touchbar Support

Slomo supports now the new Touchbar. Skip easily through your loops and adjust your playback speed.

"Which file formats are supported?"

Slomo handles .wav, .aiff, .mp3, .aac, .m4a, .m4b and .caf-files. Currently no .ogg, no .flac.

"I cannot drag a song onto the app from iTunes"

Be sure to use your local library. Tracks from an iTunes server or another computer's library can't be dragged anywhere.

"Nope, I just can't open that song"

It is probably a copy protected track, which we do not support for now. Nevertheless those are pretty seldom these days.

"Why is there only one track regardless of stereo or mono files?"

The waveform shows the left channel in the upper half and the right channel in the lower half of the view.

"I've found a bug. Shall I rate the app with one star?"

Hmm..., no. Please contact us. We always love your feedback and are happy to help."

"I love Slomo. How can I spread the word?"
