Ratings and Reviews
Very nice but needs a “recents” section in the open dialog
This is *almost* the slow downer I’ve been looking for! Great clean interface (i really don’t know why most are so incredibly ugly) and it can read from the local library and my cloud services.
The one thing that seems obvious and is missing is a “recent items” section in the file open dialog. I tend to be working on a few songs at once, so why not have the top item on the + menu be “recents >” that opens up a submenu list of the last twenty files, sortable by most recent or name, and then opens them with their last pitch/time settings, markers, and loop. Then it would be perfect!
Will be upgrading to the full version, because i need more than three minutes & three semitones :)
Developer Response ,
Hi huzzam - Thank you so much for the kind words and sharing your feedback! We'll definitely consider implementing these features to the app in the future. If you have any other ideas, do not hesitate to let us know.
This app is good. I use it to listen to demos at various pitches and identify weak points in the mix.
The app would be *great* if it could change pitch and speed in lock-step, like playing a vinyl record faster or slower, with no algorithmic artifacting. You can try to keep the pitch and speed values close to each other, but it still destroys the transients of percussive sounds, as pitch-shifting algorithms tend to do. I've been searching for an app that can do that for years, but AudioStretch is the closest I've found.
Just saying… I'd upgrade & vehemently recommend it to everyone I know if it could do that. 😉
Solid app especially because it’s free!!
It’s a great app to edit my audios, I can slow them down or speed em up, lower or pitch up the tone. It’s amazing!! I just wish we could have more ways to edit the audios and to have different instruments to put behind the tracks or to go with the tracks. As of rn I can’t figure out how to put the default scale piano we get into the recording. That’s the only things I suggest. Different instruments to use with the audios and a couple more different ways to edit the tracks.
