New features
o
WaveLab is now an automation server providing scripting support for
audio file processing and file format conversion, batch processing, playback,
and recording. Scripting allows you to remotely control these WaveLab
functions, to automate repetitive tasks and optimize your workflow. In more
technical terms, WaveLab provides a "COM" interface with a high-level API
(Application Programming Interface). This API allows you to write scripts
(VBScripts, JScripts) or C++ applications, to call some WaveLab functions.
Our approach is to offer control over few but simple and powerful functions.
This API will first of all be of interest for studios and structures dealing with
large sets of files and needing automation. The API will be extended in the
future according to user requests. For details, see the document "WaveLab
Scripting.pdf" in the WaveLab\Scripting\ folder. Dont misunderstand this
feature with a macro system.
o
AES-31 support : 1) import (an Audio Montage gets created), e.g. use this to
import a Nuendo project. AES-31. 2) Export (menu File / Save special), with
several output options. Use Nuendo 2.0 rather than Nuendo 1.6, because of
the improved AES31 implementation. With Nuendo 2.0, you can create
markers that will be interpreted as WaveLab specific markers when
exporting a AES31 project, this by adding some special keywords to the
marker name (note: you have to create a marker track in Nuendo). Like this:
CD track start marker -> "[t-start]"; CD track end marker -> "[t-end]"; CD
track splice marker -> "[t-splice]"; CD track index marker -> "[t-index]";
examples of valid marker names: "Hello [t-start]"; "This is [t-end] the end"; "[t-
splice] Bye". When importing the names, WaveLab remove the codes when
displaying the markers ("[t-start]", etc.). WaveLab will export the markers with
the same convention (imported back to Nuendo). In other words, it is possible
to design a project almost ready to burn by creating the proper markers in
Nuendo.
o
Audio Error Detection and Correction tool (menu Analysis). This function
allows scanning a file for errors, to mark them, and to optionally repair them.
Support for ShuttlePro tm . Load the supplied WaveLab ShuttlePro
preference file (Tools folder) and then enjoy the jog and shuttle capabilities
(we recall that F10 must be pressed to activate the jog and shuttle mode in
WaveLab). When the jog and shuttle mode is activated, pressing the Space
bar has now for effect to immediately stop playback at the hot point. Finally,
an ASIO driver with a rather small latency will give better results. Other pre-
programmed ShuttlePro buttons: zoom in/out, undo/redo, start/stop playback,
play selection, toggle loop mode, toggle Jog & Shuttle Mode, Open file, save
as.

o
Extended File format support : now WaveLab can save in all available file
format from all places (recording, CD grabbing, render, batch, etc.). You will
find a new file format dialog in all these places. It is important to note that
Resampling and Mixing (proposed in this dialog) happen as the very last step
of the rendering chain, after the Master Section processing. For this reason,
for high-quality mastering, it is not advised to use these options which are
primarily intended to facilitate certain works. For Mastering, use the
Resampler plugin and mix options from the Master Section, followed by a
dithering process.
o
MPEG Layer 2 support : WaveLab can now read and write this type of file
(also called musicam files). It is possible to create raw mpeg files, or RIFF
wrapped files (files with a .wav extension, compliant with the Broadcast Wave
Format).
o
Windows Media 9 : WaveLab now supports the full set of Windows Media
Encoders 9 (import/export). Of course, Windows Media Player 9 must be
installed for this.
o
Vorbis Ogg file support (import/export).
o
ADPCM file format support (Dialogic and Microsoft)
o
ASCII/Excel file format support. There are two purposes for this: to import
specially generated waveforms, created e.g. in Excel (educational and
experimental purposes). To visualize (and possibly edit) any sample value, in
text form (e.g. in Excel). These files are not compact: avoid creating huge
ones. Note: when using 32 bit float files, the format is not 100% lossless
because it is not possible to express a binary floating point value in textual
decimal form without a very small precision loss.
o
Updated version of MP3s Lame encoder (v3.93.1).
o
MP3 files can now be created with a RIFF header (that is, a file with a .wav
extension).
o
MP3 and WMA Tags: there is now an option to automatically set the title
tag as the file name.
o
Header-less PCM files can now be created.
o
Audio-CD grabbing: CD-Text can now be imported . CD-Text is also
carried over MP3/WMA tags if saving in these formats.

o
Audio-CD grabbing: it is now possible to grab the entire CD,
including audio in pauses and all sub-indexes . Use the Convert to
Audio Montage or Create Cue-sheet functions for this. This function
currently only works with Plextor drives, as far as we could test. Only Plextor
supports correctly the official command set for this function. Since Plextor
drives are from far the most widely used drives among professionals, we
decided not to spend the time to support various specific methods of other
manufacturers, at least for the time being.
o
Audio-CD grabbing: new function to save the CD as a WAV image with a cue
sheet file (.cue file).
o
Audio-CD grabbing: the automatic renaming of tracks has changed
behaviour: track numbers are added as before but the original track names
are preserved.
o
Audio-CD grabbing: options to automatically read the ISRC codes and CD-
Text, each time a CD is inserted (or the Refresh function called).
o
Audio-CD grabbing: it is now possible to define some pre-roll / post-roll
values. When grabbing individual whole tracks from a CD, WaveLab will be
able to read a bit before the track, and a bit after. Since positioning on a CD
is only accurate to 1 or 2 CD frames, this allows grabbing for sure a whole
track.
o
Audio-CD grabbing: CDDB track recognition has been replaced with the
FREEDB system. About same functionality.
o
New function: Compare Audio CD images (Tools menu). Since
WaveLab can now extract a full disk image from an audio CD, it can be useful
to compare what has been burnt against what should have been burnt.
Basically, if you need to validate an audio CD burning session, you would
proceed as follows: 1) create a cue-sheet with CD-Image from the Audio
Montage (Render dialog). 2) Then open and burn this CD image. 3) Then
extract a CD image from the CD import dialog. 4) And finally use the CD
image comparison function. Why comparing CD Images and not Audio
Montages? Because a CD Image is the lowest level representation of an
audio CD, while the Audio Montage can contains multiple elements, such as
plugins, envelopes, etc which would make the comparison less accurate.
The comparison is smart as it takes into account the possible sample offset
of the audio data on a CD (an audio position can only be read with an
accuracy of +- 588 samples, according to the Audio CD specifications).
o
Audio selection editor : For Wave: menu Edit / Select / Edit For
Montage: Tab Edit / menu Select / Edit audio selection range
o
New function: Create Audio Montage from Wave (Edit menu, when a Wave
window is active).

o
New Master Section plugin called Silence to add silence at the start and
end of a file. Useful e.g. to generate a specific size to be filled by a reverb tail
(reverb must be placed further in the plugin chain). Of course, it can also be
used in the batch processor.
o
Sample Attribute dialog: the name field now default to the file name.
Moreover, a new button allows to extract the key from the name, if any, to set
the key/detune value. It is also now possible to enter the key by number. It is
now also possible to edit key and velocity range information. Information is
preserved when converting between AIFF and WAV formats.
o
AutoSplit: it is now possible to choose either WAV or AIFF format as file
format output.
o
AutoSplit: it is now possible to generate BWF (Broadcast Wave Format) time
stamps for each split file.
o
AutoSplit: it is now possible to generate file names including the MIDI note
number.
o
Recording: there is now an option to confirm recordings discarding, and
another one to confirm the dropped marker names. For this last case, there is
now the possibility to specify a marker delay (e.g. if you have pressed the
marker hot-key with a delay of 2 seconds, you can yet create the marker at the
right position, as far you can roughly estimate this delay).
o
Recording: it is now possible to save/restore all settings as presets.
o
Recording: a new option allows you to choose if you want the recorded file to
open in WaveLab or not (ON by default)
o
Audio Montage: Render dialog: new option Open as new Montage. The
source montage is rendered as usual into an audio file, but then an Audio
Montage is created, and the possible markers are translated from the audio
file to the montage. E.g. this allows you to take a 96 kHz montage with CD
markers, and render it as a 44.1 kHz montage ready to be burnt.
o
Audio Montage: when rendering one or more clips as individual audio files, it
is now possible to specify some options like bypass Master Section,
Bypass clip plugins, Bypass volume/pan envelopes.
o
Audio file open dialog: there is now an option (check box) to open the audio
file(s) directly into an Audio Montage created for the occasion.
o
Audio Montage, CD tab: while checking if a CD is valid, if you get the
message: "some clips are not included inside CD tracks." the concerned
clips now get selected, to ease the search of the mistake.

o
Audio Montage: the option Rename selected clips as their audio files has
now the option to add a time stamp to the file name.
o
Audio Montage: Time format dialog: it is now possible to show time code as
an absolute number of frames (e.g. 294788 rather than 01:05:30.38)
o
Audio Montage: CD Tab: new option "Show times relatively to CD's absolute
zero". By default, this is off and times are displayed from the logical zero (the
absolute zero plus 2 seconds).
o
Audio Montage: Clip tab, new function Update BWF time stamps (selected
clips). This function only makes sense if each clip refers to a different audio
file, and if each clip refers to the very start of the audio file. Each audio file
which sees its time stamp updated gets open in a window, as reminder to
save it.
o
Audio Montage: in the file browser tab, it is now possible to use the keyboard
(a-z) to jump directly to the first file name starting with a given letter.
o
Transport bar: all settings are now global to all windows, if the option is
activated in the preferences (default)
o
Preferences: it is now possible to specify an extra VST plugin path. It is also
possible to specify if you want the shared VST plugin folder to be ignored or
not. It is also possible to specify sub-folder names: any plugin located in these
specific sub-folders will be ignored by WaveLab. This is an easy way to
remove unwanted plugins (unused in Wavelab, or conflicting plugins). Note: if
WaveLab cant start because a plugin crashes during the start-up, you can
press and maintain pressed [Control] and [Shift] while running WaveLab: no
plugin will be loaded and so youll be able to adjust the VST path preferences
as described above.
o
CD Project: it is now possible to set the ruler size for CD or DVD, and to
define the media size (red indicator on the ruler)
o
ASIO: in the preferences, there is now an option to start ASIO streaming as
soon as WaveLab is started. The default option is OFF, that is, ASIO
streaming only starts at the first playback or record request.
·
Main bug fixes
o
VST Dynamics: this plugin would not work on all systems.
o
Audio Montage Full Cloning: a bug that would happen in certain rare cases.
o
Several other bugs
