I am working on a research project related with
wav files. I have
wav files of different songs from different artist. I am going to extract some information/features from these audio files. Before extracting features, I thought it would be always better to have all the wav files in one uniform format/standard. For that I brought all my wav files into 44100Hz sampling rate and 16 bits bit depth. But I am stuck at one point. I cannot find out a way to bring all the wav files into one volume level.
When I listen to my songs, I hear that some files are in a higher level in terms of volume and some are low. So that I have to always adjust the volume once a new song(wav file) is started. I think those files have to be in a same volume level in order to be used in my project.
I searched about this and found
iTunes for MAC has got the support for this as described here. But I am not sure that whether I can export
wav files from
iTunes or not into my required format.
MP3Gain is one other tool which is capable of this task. But it does not support mp3 files.
My question is can I bring my all sound files into one volume level? If it is possible, what are tools for that?
