问题
I am creating an Android application using Phonegap. I would like to record a sound (for example, a doorbell), and detect if that sound is heard again. Is there any sound recognition plugin for Phonegap?
If not, how can I access the frequencies of the recorded sound (for example, in an array), so I can manually write an algorithm to compare the two audio files? Is there any audio format which stores data in that form?
Thank you
