A You are swimming in 'A's, and this app will detect and record them! A
This specialized app listens for six octaves of the note 'A' in your audio environment, and can record all the 'A' notes it hears. Then you can upload that recording to a special website which collects worldwide recordings of 'A's. On that website, you can play several contributed A recordings simultaneously.
Only A can also send out an OSC stream that can be picked up by apps and desktop programs that can understand OSC.
Written for the Tuning Worlds festival, a project of Aune Head Arts, Dartington, England.
Slight update so it can compress and upload again. Now it must run in iOs 7.1 or later!
It's alos been updated to look better on new devices, and the info file has been updated!
With Family Sharing set up, up to six family members can use this app.
