Does librosa load normalize?

librosa does not normalize wave file between [-1, 1]

I down sampled to 16 and also up sampled to 32 to work with librosa. Both of these files produced the same min-max range after going through librosa.

What is the default sound in librosa when loaded?

librosa uses soundfile and audioread for reading audio. As of v0. 7, librosa uses soundfile by default, and falls back on audioread only when dealing with codecs unsupported by soundfile .

Can librosa load mp4?

Since librosa can load MPEG4 audio (when suitable dependencies are installed), I would recommend downloading that, and loading it directly.

What is SR in librosa?

The sampling rate --- typically fs in the digital signal processing literature, or sr in librosa --- is defined as 1/ts, where ts is the amount of time (in seconds) between successive samples. Equivalently, fs is the number of observations per second in the discretely sampled signal.
