Some learners use audio recordings of Ancient Greek as a way to learn.
Sometimes the complaint is that the audio is read too fast.
Sometimes learners want to re-listen to clips a couple times.
Here's a possible solution.
SoundScriber is a free, downloadable little program.
It plays audio files.
It allows you to vary the speed.
You can also tell it to repeat every x seconds of a clip y times.
When it repeats, it can also overlap a small portion of the previous clip.
Easier to use than describe.
