You have many ways by which you can process audio and video. SoX is the best tool for command line audio processing with ability to add echo, reverb, fade, crossfade, filter out noise, add flanger, panning and so on.
Audio junkies should know. Now SoX supports a lot more than what it did when I wrote an article long ago. Google for it. Then you have audacity, a nice graphical tool for zoom audio waveforms and edit them. You can convert video to audio using ffmpeg. $ ffmpeg -i foo.mpg foo.mp3 It is that simple. Audacity is a very powerful tool. It is a GUI that runs on many platforms so you should be able to edit audio fairly well. You can combine mp3 files or split them using mp3splt. You can id3 tags using id3ed. You can easily amplify the volume without the annoying clipping effect if you combine it with a bandpass filter with sox. Or you could use normalize for the same. If you play a lot of songs in unison you can use normalize which does two passes and modifies the volume levels of all audio files. Now let us talk video. mencoder and ffmpeg are excellent. you have transcode which can do things these two can't. You know that video is nothing but image frames shown at high speed right? You can get back images using a simple mencoder command line. It is in my mplayer article. You can create a DVD ISO that can play on your home DVD player using dvdauthor and mencoder. For audio and video player you also have vlc. ffplay, totem and so on. For youtube video download you have youtube-dl , a python script. If you want to add subtitles mplayer can . You also have OSD menus that add a transparent layer on top. You can probably come up with a home multimedia system with these tools. -Girish -- Gayatri Hitech http://gayatri-hitech.com _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
