- Audio Compositor 2.0
-
- Introduction
- ============
-
- Audio Compositor is software for realizing MIDI data as digital audio.
- When the input comes from a standard MIDI file, Audio Compositor can
- realize it as a Windows .WAV file, or if your processor is fast enough
- it can play the MIDI file in real time. When the input is a MIDI keyboard
- attached to your computer, Audio Compositor behaves like a normal sound
- module, though its capabilities will again be limited by the speed of your
- processor. Audio Compositor also provides a graphical environment for
- editing samples and patches.
-
- Audio Compositor runs on Windows 95, and on Windows NT 3.51 or above. It
- does not work on Win32s, though an earlier version that did is still
- available from the web site at this writing.
-
- Version 2.0 of Audio Compositor is shareware; please consider registering
- it. Registration unlocks certain features of the program that are absent
- from the unregistered version. For details, see "Register Audio Compositor..."
- on the Help menu. In its unregistered state, Audio Compositor may be freely
- distributed so long as the program and all supporting files are retained and
- unmodified.
-
- While Audio Compositor is fully documented in AC.HLP, you can set up the
- program quickly by following the directions below. The distribution includes
- a set of classical guitar samples and a MIDI file with which you can do a test
- run. Please note that these demonstration files were chosen for their small
- size and not for their quality!
-
- Questions, suggestions, and bug reports may be directed to mitchell@eden.com

- Installing Audio Compositor
- ===========================
-
- There is no "setup" program for Audio Compositor; simply unzip the distribution
- into a directory of your choice. If you unzip with the directory structure
- intact, there is nothing more to do; otherwise you must move the guitar samples
- to a subdirectory called Samples\Guitar under the directory where the program
- is installed. For example, if you placed the files in
-
- d:\Dubious-looking-software\Ac
-
- then the twelve guitar samples should be placed in
-
- d:\Dubious-looking-software\Ac\Samples\Guitar
-
- If you set up an icon or shortcut to start Ac.exe, set the working directory
- (the "Start in" field under Win95) to be the directory where Ac.exe is located.
-
- To deinstall Audio Compositor, delete the files that came with the
- installation, plus Ac.ini in your Windows directory.
-
-
- The Leyenda Example
- ===================
-
- Audio Compositor comes with one MIDI file, an abbreviated version of Isaac
- Albeniz's "Leyenda" that is prepared to work with the included guitar samples.
- To try it:
-
- 1. Run Audio Compositor (Ac.exe), choose "Open Midi File..." from
- the File menu, and open Leyenda.mid.
-
- 2. From the Edit menu, choose Settings.
-
- 3. Move to the Constants tab in the Setup dialog. Confirm that Output
- Sample Rate is set to 22050 (this is the highest rate that the
- unregistered version supports.) Be sure that Stereo Output is not
- checked (if you have a Pentium or faster CPU, this precaution is
- probably not needed, but the guitar samples are monophonic anyway).
- Attenuation should be set to 12 dB for this file.
-
- 4. Click OK to dismiss the Setup dialog.
-
- 5. Be sure that the the Audible button (the loudspeaker icon) is
- depressed; this turns on real-time output.
-
- 6. Click the Go button.
-
- If you hear gaps in the playback, Audio Compositor is not running fast enough
- to create its output in real time. This won't affect its ability to produce
- good .WAV file output. To create an output file, repeat the steps above but
- specify an Output File Name under the Files tab of the Setup dialog (you will
- need about 5 megs of disk space).
-
- Note: In the Leyenda example, you will hear some hesitation after each of the
- strummed chords later in the piece. Guitarists generally don't try to play
- this passage in strict time, and the MIDI file contains tempo changes meant to
- approximate the usual practice. It's not a symptom of any timing inaccuracy
- in Audio Compositor.
