I've an audio file with me (Audio File), who's volume is too low. I need a increase the volume just enough so that I could understand what is being said in the audio file.
Is is something which could be done in Matlab? If yes, then can we do it with Matlab code, so that the whole process could be automated. ( I've quite a lot of audio files like this). I just need a quick and dirty solution which could work on such audio files. I haven't done any audio signal processing, so kindly forgive me, if this seems like an obvious thing.
Any help would be greatly appreciated.
