New icons

Files saved with TwistedWave now have a nice icon. Here is what they
look like:

Support for metadata

TwistedWave can now read and edit the metadata present in sound files
in the aiff, wav, mp3, mp4, flac and ogg/vobis formats.

In addition to the music metadata, TwistedWave also supports BWAV and
Soundminer metadata.

A note about metadata support in FLAC files. Although BWAV metadata
can only be present in WAV files, and Soundminer in WAV or AIFF files,
TwistedWave allows you to read and save these kinds of metadata in
FLAC files. When the FLAC codec is used to convert files from wav to
flac, it used to drop all kind of metadata, and keep only the sound
part of the file. Since FLAC version 1.2.1, the option
–keep-foreign-metadata allows the codec to save all the metadata from
the WAV file in the FLAC file. These are restored when decompressing
the FLAC files to get back the WAV file. What TwistedWave does is that
it saves the BWAV and Soundminer metadata as foreign metadata in FLAC
files, so that they can be restored by the FLAC decoder.

Special pasting

When copying and pasting an audio clip from one place to another, the
transition can be a bit rough, and unpleasant. In order to smooth
things a bit, TwistedWave offers a special pasting command that can be
customized in many ways, automatically adding fades in and out to make
the transitions smoother.

The options dialog even shows a preview of what would happen when
pasting, making immediately obvious where the fades in and out would
take place.

A signal generator

A signal generator allows you to easily generate waves in many shapes,
such as sine, rectangle, triangle or sawtooth, as well as white and
pink noises.

The generated signal can be either inserted in the document, replace
or be mixed with the selected sound.

New audio unit options

There are two new options in the audio units window.

The first one offers the ability to apply the unit globally. When this
option is checked, the audio unit is not attached to a single document
anymore, but remains open for all the documents you are working on.
This can be useful in particular with visualisation plugins. A VU
meter, for instance, could be useful for all the documents you could
be working on.

The second option allows you to specify what to do with the effect
tail. The tail of the effect is the sound produced by the Audio Unit
after it has finished processing the selection. Instead of discarding
it, it is now possible to insert it in the document, or merge it with
the rest of the document.
