AudioStretch 4+

I’m not paid to write this review, idk if there are other good reviews that were paid for out there but I kinda doubt it cuz the app is genuinly a good one. it costs $10, but if u often transpose music, this is a great investment. App has a great interface and it’s and it’s transposing software sounds great as well and maintains the timbre/formant of the sound well (which can be difficult at times)

Although, one thing that I’d like to see as an added feature, if it doesn’t exist already, is the option to transpose audio by however many cents you want. The only intervals I can transpose by are 100 cent intervals, but some old recordings are tuned down a bit and in between half steps, which can make things a bit more difficult depending on how you transpose recordings.

Tapping on the PITCH control's sharp/flat buttons raises/lowers the pitch in semitone increments, but can do cent-level fine adjustments that by sub-semitone amounts by dragging left or right on the PITCH control.

Audio Stretch is quite an amazing app that makes the technical part of transcribing easy. The tempo and pitch controls are easily changed by whatever amount you desire (by either sliding them or scaling up/down. You can play a small part of a recording ‘by hand’ in the style of moving old r/r tape slightly, or even hold a sound to listen to a certain moment of your choice. Loops are easy to use.
There is a keyboard picture which indicates the pitches/overtones that the app hears at a certain spot; this is helpful to verify what you are hearing (used by itself only visually, the results might seem a bit jumbled).
Start/stop is very easy with a tap on the screen.
One note: you must own (i.e. purchase) a copy of the music (via the itunes store, for example) you are working on for the app to access it. You may not just import a stream into the app. If you have any appreciation of musicians’ relationship to their recordings and copyright, you will understand why this is. Do not expect to use/manipulate/etc. streamed recordings for free.

Hey There!

Thank you so much for the review! Glad you're enjoying AudioStretch! Keep those sweet tunes coming!

One of my hobbies is that I sing 4-part barbershop music. The most conventional way to learn our music is that we get learning tracks with your part in one ear(channel) and the 3 other parts in the other ear.
I have had other apps that also have the ability to slow down, change keys, block off sections to work but the biggest change with AudioStretch is that you can listen to a note or chord as long as you wish as long as your finger is on the screen. The feature is awesome when something is really fast or hard to hear.
You can also load your own video and do the same thing there.
The other feature that is different is that you cal load a piano bar at the top of the screen. It shows which notes are being sung and the overtones that are produced.
If you learn your notes visually, this will help.
This is the best out there to learn music. It might cost a little it is so worth it!!!!!

***Addendum***
As I mentioned earlier, I do have another similar app that has a lot of the same features. The one thing it has that AudioStretch does not have currently is the ability to keep a list of files that have been uploaded previously. It makes it easier to go back and forth to different files.
If that feature were to be added, it would have everything I need.
Thank you again for a great app!!!!!!

Wow! Thank you for the amazing review, wstuttsjr! We really appreciate it.
