This topic and the Preferences topic describe how to use SoundApp and how to configure it for handling special cases. I can be reached via e-mail (see the Notes topic), and the SoundApp home page is located at <http://www-cs-students.stanford.edu/~franke/SoundApp/>. The latest version of SoundApp can always be downloaded from this location.
Balloon help is always available to provide more information about the various preferences, menu items, and buttons in SoundApp.
Drag and Drop Interface
Playing sounds with SoundApp is simple; just drag and drop sound files onto the SoundApp icon. You need not wait until a group of sounds have finished playing before dragging and dropping more sound files onto the SoundApp icon. SoundApp will asynchronously process additional drag-and-drop requests by adding them to the queue of sounds currently being processed. SoundApp can also optionally search through nested folders dropped onto it, looking for sounds to play inside each folder. In addition, files can be played via the Play menu item.
In addition to playing many file types, SoundApp can also convert supported sound files to a number of formats. The suitcase option, in particular, creates files that can be opened in the System 7 Finder and manipulated just like font suitcases. In order to convert files, hold down the conversion key, by default the shift key, when dragging files onto SoundApp’s icon. Be sure to continue holding the conversion key down until SoundApp comes to the foreground. The conversion key can be changed in the Keys section of the Preferences dialog.
Using Play Lists
Files can be added to a Play List by dragging files or folders into it from the Finder or by using the Add menu item. In addition, files can be added to a new list by holding down the modifier key specified in the Keys section of the Preferences dialog box while dragging files onto SoundApp. By default, this is the option key.
If the Macintosh Drag and Drop Manager is installed, files can be re-ordered by dragging file selections. Files can be dragged out of the Play List and converted files will be placed in a folder on the desktop.
Play Lists can be saved and then opened later. This can be used to group a favorite selection of sounds for easy playback. SoundApp can have any number of Play Lists opens at a time, and files can be dragged between them.
Clicking the “Repeat” check box before playing will cause SoundApp to play the sounds in the list continuously, and enabling the “Shuffle” check box will cause the files to be played in a random order when either of the Play buttons are clicked. The Play and Convert buttons play or convert the currently selected files; the Play All and Convert All buttons will play or convert all the files in the list regardless of the selection. Typing the first few letters of a sound’s name will cause that sound to be highlighted. Double-clicking on the selection will play the selected files.
Controls
While sounds are playing, typing command-period will halt playback for the current selection of files dropped onto SoundApp. Typing period will halt the playback of the current sound and play the next one, if any. In addition, the left and right arrow keys can be used to skip to the next sound or return to the previous sound, respectively. Typing semicolon will stop processing after the current file has finished and the space-bar pauses and resumes playback. The “+” and “-” keys can be used to change the volume during playback. Note that the volume is relative to the system volume as set in the “Sound” or “Monitors & Sound” control panel and the volume can range from 10% to 150%. Volumes greater than 100% may be helpful in boosting quiet sounds, but can cause undesirable distortion in loud sounds.
An optional Controls palette can be displayed which contains buttons that mimic the controls of a CD player. The buttons are in order: convert all files in the current play list; play all files in the current play list; toggle pause for playback; stop processing; jump to the previous file; jump to the next file; and stop processing after the current file has finished. If the command key is held down while clicking on the convert or play icon, only the selection will be processed.
The Controls palette can be displayed using either the “Display Controls Palette” preference in the General pane or the Show Controls menu item in the Options menu.
Memory Allocation
SoundApp allocates memory for processing in the System Heap using the temporary memory allocation facilities. MOD playback can alternatively allocate memory from SoundApp’s partition if the appropriate preference is set in the MOD pane of the Preferences dialog.
Notes
• MOD/S3M/MTM conversion only extracts the instrument samples.
• Some of the more unusual MOD formats cannot have their instruments extracted.
• Some rare WAVE compression formats, compressed VOC files and some sub-types of Sun Audio files are not supported.
