I'd like to build something a little like the LiveEffect sample in the Google/Oboe library.
However, I want to affect the audio selected from a file chosen by the user rather than the microphone input. I do not need the input.
There's no example in the Google/Oboe repo of how to operate on a file.
Does anyone have an example or guidance so I can let the user choose a file from their local storage, then (and this is the bit I'm missing) pass the audio across the JNI bridge to my oboe app?
I do the need low-latency capability of Oboe as I'm going to affect the audio in response to motion data.
Any guidance gratefully recieved.
For anyone passing by in search of a similar solution, here's how I solved this
mixAudio()
method bearing in mind all the rules for real-time processing in Oboe.I also needed to do this on the block because I have a fixed window operation. to do this, I adapted the SampleBuffer class to add a method that would pull block data into mixAudio(), but that's only specific to some cases.
I hope that helps someone in the future.
