In fact, there was already an attempt to do this in Matlab GUI, but that did not work out well and octaudio seems like it contains all the basic functionality we need plus all the power of Qt.\r\n\r\nThe idea is to have a new type of track, which would basically show spectrogram instead of the samples.\r\nThen there could be some basic image editing tools and a way how to get the new image back to octave.\r\n\r\nAnd some more minor things concerning the current state of octaudio:\r\nI really miss being able to browse the history using up-down arrows.\r\nAlso the history command does not seem to be working.\r\nIs there (will there be) a way how to select a range of samples in a track?\r\nWhen I do plot from the command window I get a fltk window, but I cannot close it or do anything with it. \r\nThe audio settings should be persistent between sessions.\r\n\r\nI am using Octave 4 on xubuntu 64bit, if that is any help.\r\n\r\nThanks\r\nZdenek Prusa\r\nLTFAT team"},"comment":{"url":"https://api.github.com/repos/antonrunov/octaudio/issues/comments/115334624","html_url":"https://github.com/antonrunov/octaudio/issues/1#issuecomment-115334624","issue_url":"https://api.github.com/repos/antonrunov/octaudio/issues/1","id":115334624,"user":{"login":"susnak","id":7150152,"avatar_url":"https://avatars.githubusercontent.com/u/7150152?v=3","gravatar_id":"","url":"https://api.github.com/users/susnak","html_url":"https://github.com/susnak","followers_url":"https://api.github.com/users/susnak/followers","following_url":"https://api.github.com/users/susnak/following{/other_user}","gists_url":"https://api.github.com/users/susnak/gists{/gist_id}","starred_url":"https://api.github.com/users/susnak/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/susnak/subscriptions","organizations_url":"https://api.github.com/users/susnak/orgs","repos_url":"https://api.github.com/users/susnak/repos","events_url":"https://api.github.com/users/susnak/events{/privacy}","received_events_url":"https://api.github.com/users/susnak/received_events","type":"User","site_admin":false},"created_at":"2015-06-25T17:26:45Z","updated_at":"2015-06-25T17:26:45Z","body":"I see. I think having a spectrogram as a special view of multichannel track is a good idea.  There is maybe a slight problem with the sampling rate as the spectrogram is usually computed using a window with some step in samples.\r\nIn some cases we even have \"spectrograms\" with  different windows and different time steps for each frequency channel and the step is not even integer. In such cases we store individual frequency channels as vectors of different lengths in a cell array.\r\n\r\nPlease let me know if I can be of any help.\r\n\r\nZdenek\r\n\r\n"}}
