Elliot Stein used the Pro Sound Digitiser in a theatrical production. Did it work?

Perhaps the best way to review software is under actual field testing conditions and I had just the project in mind! That project is the premiere of a new stage show in the Edinburgh Fringe Festival that I'll be directing entitled 'The Ballad Of Halo Jones', based on the popular series from 2000 AD Comics. Unique to this show will be the extensive use of computerized special effects, all being produced by the mighty Atari ST.

We decided to use the ST to produce sound effects for the show as well as to record, edit, and manipulate several voice-over narrations. Since computers are capable of only digital sounds, a digitiser such as the hardware supplied with Pro Sound Designer or it's competitor 'Replay' (by Microdeal) must be used to bring the analogue sounds of the 'real world' to the ST.

First thing to do is to plug in the hardware, however unlike the hardware portion of Replay which very conveniently plugs into the ST's side cartridge port, Pro Sound Designer connects inconveniently through the ST's rear printer port. For many ST users, like myself, who use their printer a great deal the constant plugging and unplugging of the Pro Sound Designer's hardware and your printer cable will be a constant and irritating nuisance. In addition as Eidersoft do not yet have the plastic cases to their sound sampler the hardware's components are irresponsibly exposed and vulnerable to damage from static electricity as well as from other unforeseen circumstances. The hardware consists of the exposed circuit board, three chips, the printer port connection, two wires to connect to a nine volt battery (which the consumer needs to purchase) and two 3.5mm audio jacks. Connecting the hardware into the ST is as easy as plugging in your printer cable. Once connected to the ST, the lower audio jack plug connects to the source that the digitiser will be taking the sound from, such as a microphone or a stereo system. The top plug is for the hi-fi option which is £14.95 extra if you choose to purchase the additional hi-fi upgrade kit. This will allow you to play your sound samples back through your stereo system instead of through the ST monitor's low fidelity speaker.

ACTION!

For the Halo Jones project, we decided to use the hi-fi option to send the sampled sounds to a four track tape recorder. The clumsy, aesthetically dismal design of the external hardware is quickly forgiven as the Pro Sound Designer software is booted-up. The main work screen is probably the best designed and most attractive screen of any serious application software for the ST or most other computers. Unlike Replay's restrictive keyboard-only operated screen, the Pro Sound Designer features mostly mouse operated icons. In the centre of the screen is the Waveform Display, an oscilloscope-like representation of the sound entering the ST from the external source which is used to set the volume levels of the incoming sound. Across the bottom of the screen are several icons resembling the controls on an ordinary tape machine and which operate in a similar fashion.

After getting our sound levels from the Waveform Display, we began to record a brief monologue performed by one of our actors. We merely clicked on the record icon and, as the actor spoke, the Pro Sound Designer recorded every word of his thirty second monologue. As in recording with other types of media, the speed used to record the sound is relational to the quality of the sound. On a normal tape machine, recording at a high speed would give far better quality and clarity than on a slow speed and the same holds true for sound sampling on the ST. Sampling at the high rate of 30 kHz gives far crisper and cleaner sounds than at 3 kHz. There are consequences in using faster speeds though. The faster the speed used to sample, the more memory is consumed which is, I suppose, similar to a tape machine where higher speeds use up more recording tape.

Pro Sound Designer conveniently offers a choice of all speeds from 3 kHz to 30 kHz. We chose the default speed of 8 kHz which enables roughly 30 seconds of memory storage on a 520 ST. Once recorded, selecting the Playback icon on the bottom of the screen enabled us to listen to the sample that we had just recorded. There is even a reverse play option which plays the sample backwards! To halt the sample before it's playback is finished, you may press the space bar and any other key will repeat the sample. Just as recording has a convenient mouse-operated speed selector, the playback has an identical control enabling a versatile selection of playback speeds from 3 kHz to 30 kHz. For the voice of the actor, who portrays the voice of a computer which is operated by intelligent mice, we decided to play back the sample at a faster speed to achieve a higher-pitched distorted voice.

CHANGE THE SOUND

Once a sample is recorded, the long rectangular window above the controls displays the wave of the sampled sound. Over the sampled sound display is a bar which displays the current positions in memory of the left and right memory pointers as well as the distance between both pointers. The two memory pointers are used in editing the sound sample and are controlled by the four pointer adjustment icons which allow the pointers to move either way across the displayed wave. To edit the sound display, the left pointer is moved to the beginning and the right pointer to the end of the segment. The wave between the pointers is the segment which will be edited. Pressing Reverse Sample reverses the sample between the two pointers and allows you to play it backwards. We used it to twist a segment within a song to create a very disturbing effect in the music.

'possible use in film ... television ... theatre'

Cut allows you to delete a section of sample wave for fine editing of the sound sample. Transparent Copy allows one to overlay the sound between the two pointers onto another section of the sample. This can be used for creating echoes, harmonies, or even building the illusion of thousands of people laughing from one solitary laugh. We used this function in Halo Jones to create the illusion of the noises of a crowd of thousands of people from a sound sample of two actors talking in a studio! Block Copy allows cut and paste operations between various sections of the sampled wave. It also allows for the chronological re-arranging of the sample's ingredients. For better accuracy in editing various sections of the sample, the Magnify and DeMagnify keys allow zooming-in or zooming-out on any specific portion of the entire sound wave. For example, one may choose to view the entire wave for a two minute sample or choose to view a detailed enlarged fraction of one second of a sample. Using the Magnify and Cut keys, we were able to remove a very brief space between two syllables of a word from an actor's speech which had a distracting background noise on it. The final control on the bottom of the screen is the Loop option which allows the playback to be heard over and over.

AUTOMATIC OPERATION

The function keys display is on the left hand side of the screen. Used to program the ST's function keys so that a selected part of a sample may be assigned to each key, it remembers the speed and location of the sample and plays it back at the touch of it's designated key. Using the many sound samples included on the Pro Sound Designer disk, it is possible to easily create an eight button drum machine. The function key's information can be saved to or loaded from a disk at any time. On the right hand side of the screen are the waveform controls. The Automatic Play icon enables an outside noise source to trigger playback. To use this option merely set the sound level that you want to trigger-off the Automatic Play then click on the Automatic Play and the Play icons. If you set the level for automatic play at seven, then as soon as a sound makes the Wavelength Display hit seven, the prepared sample will play back automatically. The instruction manual which comes with the program suggests using this option as a burglar alarm or as an answering machine.

There is also an Automatic Record option which operates similarly to the Automatic Play It's extremely useful for recording something which may have a long pause at the beginning. In the Halo Jones project, we used Automatic Record so that the sampler would begin recording as soon as the actor begins to speak. This helped relax the actor, and he was able to begin when he was absolutely ready without having to be cued. A Lock option allows the Automatic Play and Record functions to reset themselves and continually operate from sound control.

EDITING THE SOUND CHIP

Also on this section of the screen is the Hi-Fi output for those who choose to purchase the additional option, an option to change the colour of the waveform indicator, a Pause Waveform which freezes the screen's display until it is pressed again, and options to Save and Load sampled sounds. The most unusual function on this section of the screen is the Edit Sound Chip. As you click on the Edit Sound Chip option, a new screen lowers across the sound sampler screen. Both the Edit Sound Chip and the Sound Sampler are entirely different programs. None of the sampled sounds can be used in this section of the program since sounds are produced by direct editing of the ST's internal AY-3-8910 sound chip. On all 16 registers of the three sound channels, the sound editor allows for control of pitch/ frequency, sound envelope shape, tone, noise, sustain time, noise frequency, as well as software register controls.

Though there have been many other programs which allow for the creation and manipulation of sound and noise in this way, many of them public domain programs, this is the best designed and most easy to use. A different set of function keys allow you to allocate to them different sounds and noises and a save/load choice allows for disk storage. For the Halo Jones project, we were able to use the Edit Sound Chip Program to create sound effects of laser guns, explosions, and background noise of heavy machinery.

To use the various sounds created in your own programs, there is a utility on the disk that allows you to turn them into a format usable by ST Basic, Fast Basic, C, and other assembler programs. There is also a routine for using sound samples in your own programs.

CONCLUSION

Pro Sound Designer is extremely good value for money, with possible uses in many different aspects of film, radio, television, or theatre production as well as computer programming, personal entertainment, and music. Even though sound samples created by Pro Sound Designer lack Midi compatibility, it is still an invaluable tool for studio or live production. For those musicians who must have a Midi compatible sound sampler, it is rumoured that Eidersoft is planning to market an upgraded version of this program with Midi compatibility.

For the Halo Jones project it performed remarkably well, allowing the editing of a surprisingly versatile choice of sound samples and effects without consuming an unreasonable amount of valuable time in doing so.

Eidersoft certainly deserves praise for marketing a product of such quality for the extremely reasonable price of £57.
