De final release van Audacity versie 2.3.3 is uitgekomen. Deze opensource-audio-editor, die beschikbaar is voor Windows, Linux en macOS, kan geluid opnemen, en wav-, aiff-, ogg- en mp3-bestanden importeren en exporteren. Het programma heeft een ongelimiteerde undo-functie en heeft daarnaast een grote verzameling effecten aan boord, zoals fade-in en fade-out, echo, tempowijziging en ruisonderdrukking. Meer effecten kunnen eenvoudig worden toegevoegd, want het programma ondersteunt zowel vst- als ladspa-plug-ins. De releasenotes voor deze uitgave kunnen hieronder worden gevonden.
Maintenance release2.3.3 is a maintenance release to reorganize the structure of the underlying code. This is so that we can make better changes for the user experience in the future.
There are no new and almost no changed features in this release. However, we have fixed many long standing bugs, at the same time as making the restructuring. We are also taking the opportunity to retire some features which are better done by other approaches.
Earlier we had set ourselves a target of 20% live bugs out of total bugs by August 2019. Two years ago 35% of bugs were live bugs, and the live bugs total was just over 600. We actually met our target early, by 1st June 2019. As at 1st September we were at 16% live bugs with just 356 live bugs. See this table in the Audacity Wiki.
Two bugs we fixed which noticeably change behavior are:
Quality slider now works for AAC/M4A ExportAn important bug-fix for this release is that we have finally made the Quality slider work when exporting AAC/M4A files. Formerly, although you could move the slider, the setting of slider was ignored by Audacity and it used always a constant bit rate (CBR) 196 kbps (stereo) file or 98 kbps (mono) file.
This was P2 Bug 344 - M4A Quality slider has no control of bitrate setting or AAC quality
Leading blank space treated as silence on ExportFor this release we have added a feature where by default when exporting audio any leading blank space in the tracks or project to be exported is treated as silence and appropriate leading silence will pad the exported audio.
Previously many users were confused when they had carefully positioned their audio with an initial offset (white/gray space) that when they Exported the track this offset was ignored and the exported file started immediately with the audio with no offset.
This particularly confused multi-track users who export and subsequently re-import tracks and are surprised/puzzled when their tracks no longer line up properly.
This makes for greater consistency in Audacity with regard to pre-existing behaviors:
There is a new option in Import/Export Preferences where you can turn this off and revert to Audacity's previous behavior with leading blank space ignored on Export.
- leading blank space has always been treated as silence when playing such an offset audio track
- if a track has embedded blank white/gray space between audio clips, upon export those embedded chunks are rendered as silence to preserve the relative positioning of the clips.
- Mix&Render has always preserved leading blank white/gray offsets
This was P3 Bug 1904 - Audio offset not honored in Export/Export Multiple/Export Selection
Exports are now based on "What you hear is what you get"From this version onwards When making multi-track exports the export will be based entirely upon the track hear when preview playing the audio in the project prior to Export.
I also means than any grayed-out tracks will not be exported.
Formerly with the Solo Button behavior set to the expert mode "Multi-Track" in Tracks Behaviors" preferences the exports were instead based on the state of the Mute buttons, using the Solo buttons could leave some tracks grayed out and not playable on preview, but still exported on Export.
Users who leave the Solo Button set to its default Simple mode will notice no difference as a result of this change.
This was P2 Bug 2213 - When Solo button is "Multi-track" Export is not accurate - can lead to data loss
Equalization effect splitThe former Equalization effect has now been split into two separate effects. We did this as part of fixing some bugs with the effect:
End-of-life retired functionality
- Filter Curve - equalization using drawn curves
- Graphic EQ - equalization using sliders
For this maintenance release we have decided to withdraw some pieces of functionaality which are considered to be no longer useful or relevant.
Nyquist Workbench End of LifeThe optional module Nyquist Workbench has been declared obsolete for version 2.3.3 onwards.
We plan to replace it later with a modern alternative Nyquist IDE. A lot of the important functionality is already built into the Nyquist prompt in Audacity.
Vocal Remover End of LifeWe have finally decided to no longer ship the legacy effect Vocal Remover with Audacity. It has been superseded for a while now by the newer and more powerful Vocal Reduction and Isolation effect. We upgraded the effect slightly with this release, so that it now can also do exactly what the old effect did.
New users who install 2.3.3 as their first Audacity will not see Vocal Remover in the effect menu. Upgraders from earlier versions of Audacity will still find this legacy effect in their effects list (because it was supplied as a Nyquist plug-in). If you no longer wish to see it in the Effect menu simply mark it as Disabled in the Plug-in Manager.
On-Demand loading of aliased files End of LifeAudacity previously had a feature where Audacity projects could depend on uncompressed audio files (for example WAV and AIFF) that were stored outside the Audacity project and folder. This saved space but was rather dangerous, as the project could become unusable if the files were moved or renamed.
The space saving made some sense back in 1999 when disk storage was more expensive. Nowadays it does not make sense. It causes far more problems than the space saving is worth. Previously we had defaults set to always copy audio into projects, and not try and save space. Now we have removed the option of this ill advised space saving. Audacity will still work with old projects that do this, but for new projects audio will always be copied in.
Normalize on Load featureAudacity previously had a 'mis-feature' called 'Normalize on Load' which gave the option of always normalizing newly imported audio (an option that was settable in preferences). Normalizing or alternatively compression should usually only be done as one of the last steps in producing audio, for example if one knows the audio is destined to go into an MP3 file or CD.
