LAoE

LAoE means Layer-based Audio Editor, and it is a rich featured graphical audiosample-editor, based on multi-layers, floating-point samples, volume-masks, variable selection-intensity, and many plugins suitable to manipulate sound, such as filtering, retouching, resampling, graphical spectrogram editing by brushes and rectangles, sample-curve editing by freehand-pen and spline and other interpolation curves, effects like reverb, echo, compress, expand, pitch-shift, time-stretch, and much more... And it is free of charge!

Why LAoE?

When I was beginning to develop LAoE, there were not many complete soundeditors on linux. The decision to write my own soundeditor came after a long time of frustration on searching a soundeditor for linux on the internet. So why LAoE, since LAoE exists?

LAoE has many (seen and) never-seen features. The clip, layer and channel concept, where each clip may have multiple layers, where each layer may have multiple channels, without logical limitations, where the layers are painted one on top of each other, in analogy to multi-layer capable image-processing tools. The uniform clip concept, where each curve, each variable parameter, each spectrum view, each envelope-, resampling-, distortion- and and and... -function curve is editable as it were a normal audio channel. Every usefull and senseless effect may be performed on them. The zoomable and editable spectrogram, where you can isolate and filter out sound-parts which are not separable in the classical sample-curve view. The all-domain sample-curve view, where audio samples may be zoomed until sample-by-sample dimension. The selections with its smooth intensity, to perform effects and functions progressively without hard edges. These are a few reasons why LAoE exists for you! Have a look at the screenshots, test it, use it, enjoy it!

LAoE today

Today LAoE is already usable and helpful for plenty of works related to soundfile-editing, but certainly still incomplete. I hope the development will keep going on for a while.

LAoE has still strong limitations on soundfile export, only .wav and .aiff are writable. Import is a little better now, since five most common used fileformats are supported, including .ogg and .mp3. Due to the poor java sound-API implementation, recording is very limited and unstable. Another strong limitation is the missing large file support, the entire file is loaded into RAM, which limits the editable soundfile length to a few tenth of megabytes instead of houndred of megabytes supported from other tools. The quality of some plugins and effects is not satisfactory (e.g. pitch shift, time stretch, disharmony...).

LAoE is currently NOT a highend-tool in terms of quality! LAoE is a software project written in java, running on JDK/JRE 1.4.0 or higher. The first platform of choice is Linux, but it also works on Windows. It contains hundreds of classes, several packages, ten-thousands of lines of code. The design is object-oriented, consists of a small core and many plugins, mostly each function or frame is a plugin. There is also a dynamic plugin loading mechanism to extend LAoE by third-party plugins.

Organisation

My name is Olivier Gäumann, alias "oli4". I am currently the owner and the only developer on this project. I'm doing this just for fun at home. LAoE is my biggest software project I have ever done. I do not count the hours of work...
