another good application that i just discovered is sonic visualizer: http://www.sonicvisualiser.org/ there's a .deb ubuntu 32bit package but i didnt see its deps... is it too late to add it on Gazpacho?
more info:Features and Design Goals Sonic Visualiser contains features for the following: - Load audio files in WAV, Ogg and MP3 formats, and view their waveforms. - Look at audio visualisations such as spectrogram views, with interactive adjustment of display parameters. - Annotate audio data by adding labelled time points and defining segments, point values and curves. - Overlay annotations on top of one another with aligned scales, and overlay annotations on top of waveform or spectrogram views. - View the same data at multiple time resolutions simultaneously (for close-up and overview). - Run feature-extraction plugins to calculate annotations automatically, using algorithms such as beat trackers, pitch detectors and so on. - Import annotation layers from various text file formats. - Import note data from MIDI files, view it alongside other frequency scales, and play it with the original audio. - Play back the audio plus synthesised annotations, taking care to synchronise playback with display. - Select areas of interest, optionally snapping to nearby feature locations, and audition individual and comparative selections in seamless loops. - Time-stretch playback, slowing right down or speeding up to a tiny fraction or huge multiple of the original speed while retaining a synchronised display. - Export audio regions and annotation layers to external files.
