How to read audio files

Question
1

I wanna read an audio file
in python i would go about it like this :

import soundfile as sf 
def read_sound(file_name: str):

    if file_name.endswith(".flac"):

      with open(file_name, "rb") as f:

          speech, sample_rate = sf.read(f)

    elif file_name.endswith(".wav"):

      speech, sample_rate = sf.read(file_name)

    print(speech[:10])

just ignore the other code , I just want to be able to get the output like this :

Java provides API for reading sound files, an official guide is here: Java Sound Programmer Guide

You can read any file in Scala:
val myAudio = scala.io.Source.fromFile(“file.wav”)

What you want to do with the file? Stream audio over Internet, store in a database, convert into different format, indeed play it via Bluetooth using AAC codec? Your question is unclear.

Then you need to study formats of audio files and decode stream of raw bytes into stream of Floats accordingly. You can also use rich Java library recommended by @jpsacha, you can import it in Scala using “import” statement.
Good luck!
