Experimental Features

Overview

These are some experimental features that are enabled/disabled in Audacity 'experiemental.h'.

Label Linking

Currently labels do not move when you cut/paste and apply effects to the audio. The Label Linking feature is very nearly ready and works for many effects, but there are still some which it needs fine-tuning for. The feature is documented in the Audacity manual.

Extra Monitoring

We'd like the audio monitor to be on by default, but this experimental modification is still causing some problems. The monitor gets switched off again when it shouldn't.

Theming

The ability to change the 'skin' of Audacity. The current method is cumbersome to use and inhibits adding new bitmaps into Audacity. One proposal has been to use wxFormbuilder to build up the theme so that we have a graphical tool for doing it.

Roll Up Dialogs

An experimental feature for hiding/showing a larger dialog dynamically. Not polished enough for mainstream use yet.

Transcription Toolbar

An extra toolbar to help with annotating recordings of the spoken voice. The full toolbar has some buggy algorithms for creating labels at spoken words. It lives on in release versions as a shortened toolbar that allows variable speed playback.

Effect Categories

Introduced to organise the very large number of effects anticipated with LV2 support. Incomplete as without user customisability the hierarchical classification proves to be not that useful in practice.

Find Notes

A spectrumLogF-like view mode with notes quantization. This is used to find notes in a recording.

On Demand Loading for FLAC

On demand loading of audio is mainstream audacity for wav files. It is still experimental for FLAC.

Score Align

Align audio with a MIDI score.

Automated Level Adjustment

Tries to find an optimal input volume, increased to get full scale deflection but that does not clip.

Misc

These features are so small, old or experimental they don't have headings for themselves.

• Right aligned Textboxes: More a user preference than anything else.
• Nyquist Inspector: More an experiment with extra panels in the main display than anything else. The intention was to make Audacity GUI elements available for scripting, first in Nyquist and then with external script.
• Spectrum View Features: Grid, skip points etc.
• Seek behind cursor: Not sure what this is.
• RealFFTF: A faster FFT than what we had. This is mainstream now and not experimental.
