I am developing audio player in android. So i want to add the details of the playing song i.e. Artist Name, Duration, Bit rate and sampling frequency.
I can get Artist Name and duration of a music file by using MediaStore.Audio.Media library
. But i am unable to get Bit rate and sampling frequency of the same file. So how can i get the same?
As i know, it can be done by using native library. But don't know how? So anyone can help me on this?
You can approximate it by dividing the file size by the length of the audio in seconds, for instance, from a random AAC encoded M4A in my library:
File Size: 10.3MB (87013064 bits)
Length: 5:16 (316 Seconds)
Which gives: 87013064 bits / 316 seconds = 273426.147 bits/sec or ~273kbps
Actual Bitrate: 259kbps
Since most audio files have a known set of valid bitrate levels, you can use that to step the bit rate to the appropriate level for display.
