laod multichannel-audio-files with readWave (tuneR)
Hi, I have a huge collection of 6-channel .wav files containing audio and sensor recordings, which I need to analyse, across all 6 channels. I'm thinking about what will be easier to do. 1.

Reading multiple files
Hi, I have 35 data files for reading. I would like get a program for performing reading of 35 files at once. All are of the type: Dados1.raw, Dados2.raw and so on.
