问题
I need to implement a voice activity detection algorithm in Java so that I can know when to start and/or stop recording audio. I am looking for an algorithm that can take either a byte[], a target-data-line, or an audio file as input. Also, a solution would preferably not use external dependencies.
回答1:
Give a look at TarsosDSP as source of inspiration: It is so far the best open source Java library to deal with Audio Detection. It is purely written in Java and briefly provides:
SoundDetection
PitchDetection
PercussionDetection
Audio Time Stretching
Pitch Shifting
IIR-filters
Check also the official paper and manual for a better grasp on the topic.
