OutOfMemoryException when processing lengthy music file

Open alanleedev opened this issue 5 years ago • 4 comments

I'm getting OOME when processing music over 5 or 6 minutes. It seems the library is loading the full length of the decoded PCM data into memory before processing resulting in memory issues.

Three years ago, I implemented this library in a very inefficient way. Need to improve.

Hi @SIY1121 , thanks for sharing! Do you have any advice on improving the performance for generating the wave data?

@chinalwb

I'm not sure but using MediaCodec via NDK might improve performance. https://developer.android.com/ndk/reference/group/media
