Overview
AudioLab16 is a digital audio postproduction application for the AmigaOS.
This document covers a specific version for the Prelude board by ACT.
Features
Direct-from-disk tecnology
Any operation is performed in direct-from-disk mode: audio-streams durations
are limited by disk space availability, not RAM space availability.
- Maximum audio streams size: 2 gigabytes each
- DOS volumes are supported: no special partitioning is needed
- Multitrack mode allows spreading a single project over hard-drives,
ram drives, magneto-optical drives, cdrom drives (AsimWare AsimCDFS3.5 required
for DOS level access to AudioCDs) operating simultaneously in direct-from-disk
mode
Realtime output through the Prelude
The results of processing, non-linear editing and mixing operations can
be monitored in realtime, 16bit mode, through the Prelude analog
outputs.
- 32KHz/44.1KHz/48KHz
- Multiple channels
Non linear multitrack editing
Non linear editing capabilities allow rearranging the temporal sequence
of audio events without changing the structure of the original streams.
The process is also non-destructive (original material is not modified during
cut&paste operations). Multiple tracks on simultaneous playback through
the Prelude are possible.
- Sixteen non linear tracks editing
- Up to eight tracks on simultaneous playback
- Multitrack graphic timeline
- Double timecode notation (hh:mm:ss:ff and bars:beats:clocks) with
autosnap-to-grid capabilities
- Drag and drop mouse control (time slipping, cloning, aligning,...)
for events and tracks
- Clear/cut/copy/paste/insert/multi-insert on up to 16 tracks at the
same time
- Multilayer mixing controls: indipendent event level and stereo pan
controls, indipendent track level and stereo pan controls, master level
controls, mute/solo switches
- Insertion/retrival of user defined text labels (comments) onto the
timeline
- Timeline views snapshot bank
Digital signal processing
Digital signal processing operators allow signal restoration, optimization
and creative modifications.
- noise gate
- delay
- flange
- multiflange
- invert
- pitch-shift
- time compress/expand
- sample rate convert
- interpolate
- decimate
- distort
- FIR/IIR filter
- reverberate
- hum-remove
- quantize
- reverse
- normalize
Waveform display
Graphic waveform display allows visual inspection and easy interaction
during ranges definition.
- Graphic waveform display for on-disk recordings
- User configurable graph resolution/speed to match different media
seeking speeds (hard-drives, magneto-opticals, AudioCDs, ...)
- Bi-dimensional zooms
- Extensive range management and monitoring: monitor range, before range
start, range start, range end, after range end ,...
Signal generation
Reference signals are usefull for testing and tuning equipement.
- Multiwaveform generator
- Impulse
- Noise
- Sine
- Square
- Triangle
- Sweep generator
AudioCD management
Audio effects libraries are available on AudioCDs. AudioLab16 can digitally
transfer the AudioCD tracks to your hard drive, to include them in your
multitrack projects.
- Transport controls (play/stop/eject/...)
- TOC management
- Digital audio transfers from AudioCDs to hard drives (compatible CDROM
unit required)
Playback triggering
AudioLab16 can be slaved to an external MIDI hardware device or to a
concurrent Amiga software application in order to playback on-disk recordings
with accurate sincronization.
- Direct-from-disk playback triggering via external MIDI devices (MIDI
interface required), applications capable of sending AREXX commands or,
manually, via the computer keyboard
- Zero-delay reaction to NOTE_ON commands: perfect sincronization with
external events
- Juke-box mode: audio streams can be selected (and played) via MIDI/AREXX/keyboard
commands
FIR filter design
The "FIR Filter" DSP operator can reads ASCII text files defining
different FIR structures. AudioLab16 can generate such text files depending
on user preferred filter specs (cutoff frequency, taps,...).
- Sinc windowing generator:
- Rectangle
- Hanning
- Triangle
- Hamming
- Blackman
- Blackman-Harris
- Up to 127 taps
- Band shifter handles low-pass, hi-pass, band pass and notch filter
generation
- Graphic displays
Audio file formats
AudioLab16 can exchange audio data files with PC, MAC, Unix, Amiga platforms.
- AIFF
- STUDIO16
- MAUD
- MAESTRO
- WAVE
- IFF/8SVX
- SUN/NeXT
- VOC
- RAW
Samplepoints formats
Raw streams can be processed and converted to common audio files formats.
- PCM 16 bit linear signed MSBLSB
- PCM 16 bit linear signed LSBMSB
- PCM 16 bit linear unsigned MSBLSB
- PCM 16 bit linear unsigned LSBMSB
- PCM 8 bit ulaw
- PCM 8 bit linear signed
- PCM 8 bit linear unsigned
- DPCM 4 bit log
