Speedible is speed reading for your ears.

Speedible allows you to control the playback speed of your audio files while maintaining its pitch so that playback still sounds normal.

Translators and transcription professionals can use Speedible to adjust the audio narration to a pace which is best suited to their workflow.

With audio recordings you generally cannot ask a narrator to slow down or speed up, but with Speedible you can do just that, and listen at the pace best suited to you.

Speedible is also perfectly suited for speeding up podcasts, or class recordings for a quick revision, as well as for slowing down foreign language lessons and recordings on a complex subject matter.

Speedible maintains the pitch even with changes in speed, which means the voice still sounds normal at any speed rather than becoming too high pitched at faster speeds or extremely low pitched when played slowly.

Difficult to Use for Transcription

Save your money. The free version of Express Scribe Transcription by NCH Software is much easier to use. This software only lets you back up in the file by pulling a progress bar which has very little control and requires you to use the mouse. Express Scribe Transcription lets you rewind by holding down F7 and has fine control. When you stop the play back of this software and restart it, it continues where it stopped. When you stop the play back of Express Scribe Transcription and resume it, the software backs up a few words in the file before continuing.

Does one thing well but could and should be much more.

This is an example of an application with almost no meaningful description for it. As a result, you have to buy it only to find out all the things you imagined it would do that it really doesn't do. For example, looking at the window you would think there was space to take notes. In reality all that is wasted space. I think that space may be for displaying a playlist, but if so, it doesn't work. There is no indication of the title of the audio file being played. The program does not tell you the percentage of speed increase. Keyboard equivalents are mostly lacking (only play and pause work). If you're looking for something to help you review audio files and transcribe notes from them, you'll find this is not the tool for the job. Hopefully it will evolve over time to have the kinds of features that would make a truly useful.

Me, damnit. ,

Needs Work

It does work for me, on the files I’ve tried it on.

But the interface leaves a lot to be desired. Loading a file via Finder doesn’t pop up the window. Sometimes the “Play” symbol shows when it should be “Pause” and vice versa.

I have not had any big problems with it, but the interface really needs event behaviors which are currently missing.

There is one other thing I find annoying: there is no slider for speed adjustment. You push a button and it goes up or down by “about” 15%. I say about because sometimes it’s 14%, sometimes it’s 18%, etc. (E.g., it goes from 0 to 14 to 32…)
