Importing Audio Files
To import an audio file, make sure FREQUIA is in Waveform view (by clicking the Equalizer/Waveform button shown below), then simply drag and drop an audio file onto the Waveform window.

Dragging audio files on to the Waveform View
FREQUIA displays up to five waveforms at a time, but you can import a virtually unlimited number of audio files.
To add a file, drag and drop it in between the existing waveforms or at the end of the list.
To replace a file, drag a new file directly on top of it.
To remove a file, right-click on it and select ‘Remove’.
Frequia supports mono or stereo .wav, .aiff, .mp3, .flac, and .m4a files.
