However, you cannot save files in the MP3 format though. Supports few popular audio formats such as: WAV, Ogg Vorbis, MP3, Snd, Smp, au, Aiff, Raw audio files etc. These presets can be used to get an in depth analysis, depending on your needs.įor instance, let’s say that you have a speech audio track, then you can choose “Speech analysis” to analyze and get a speech optimized editing session. It has few built in presets such as: Demonstration, WaveForm, Spectrogram, Speech analysis and transcription file (supports reading and writing few transcription formats too) based presets such as HTK, IPA etc as well. However, I tested “WaveSurfer” in both Windows 7 and Ubuntu 11.10 Oneiric Ocelot, (it comes as a single executable file!), and it ran in both platforms without any issues whatsoever (except for few minor glitches, more at the end of the article). So if your application has few dependencies, then you cannot know for sure if those dependencies will be included in all the (or at lest in most of them) GNU/Linux distributions. However, under GNU/Linux it can be a bit difficult, because various distributions ship different applications installed by default.
So one can create a portable app with somewhat ease, as the developers know what MS Windows/Mac OS X include by default.
I mean, creating a portable app in both MS Windows and Mac OS X might not be that hard, as those OS platforms are proprietary in nature (OS X has few open-source libraries, I guess) and there aren’t any other OS distributions, “based on” them. But still, it supports a reasonable amount of popular audio codecs and can be run multiple OS platforms such as in MS Windows, GNU/Linux and Mac OS X as well.īut most importantly it is extremely portable. And perhaps because of that, the audio format support is not as good as with Audacity. It’s a pretty good looking audio editor (plus an analyzer) that has a simple user friendly UI and is primarily optimized for speech audio tracks. However, if you don’t need all those features, and need something that’s a bit simpler, then you might wanna try “WaveSurfer”. If you’re looking for a powerful, open source, audio file editor, then Audacity is an elegant little tool that’s extremely popular, mainly due to its features (I think).
