Play mode 1. System Requirements ---------------------- Macintosh: CPU: 68030 or newer. Power Mac can be used in emulation mode. OS: System 6.0.7 or newer. Memory: minimum 1 MB for the TWE. HD: Average access time 30msec or faster. Recording Hardware/Software: CBX-D5 CBX-D3 Playback: Sample Size: 8bit/16bit Sample Rate: 11.025kÅ`48kHz Mono/Stereo/4Ch Recording: Sample Size: 16bit Sample Rate: 22.05k/32k/44.1k/48kHz Mono/Stereo Mac Sound Manager ver 3.0 is required. Playback only. 2. File menu ------------ New The New command lets you create a completely new sound file. When you choose the New command, a dialog box appears, allowing you to specify the File Type, Channels, Sample Size, Sample Rate, Fill Zero(*1), and Length. (*1) The new command allocates the new disk space to create the new sound file. Usually this space is not initialized by the Mac OS and contains some garbage. By filling zero to this file, you can get the new silent file. * If Fill Zero is on, The new sound file is silent. TWE takes time to prepare the new file. * If Fill Zero is off, The new sound file contains garbage. TWE can prepare the new file faster. This option is useful when you record something on it immediately. Open... This command opens an existing sound file that is compatible with TWE. This command works in one of two edit modes; open an existing file (original mode), or open a new copy of an existing file (back up mode). The File Backup command in the Setup menu determines which of these occur. The current mode is displayed in the wave window. The copy of the existing file is called "temporary sound file". Close This command closes the Wave window. When the edited data will be lost, TWE asks you to save or not. Choose one of these commands. [Save] Save the data and close the window. [Cancel] Don't save the data and leave the window open. [Don't Save] Don't save the data and close the window. Save This command saves the sound file. Save As... This command saves the sound file under a new name. Revert This command reopens the sound file that was last saved. Resample... This command converts the sample rate. The parameters are for FIR used for the conversion. * FIR Order It specifies the order of the FIR filter. The larger this value is, the better the sound quality you get. But it also takes longer time for to process. * Rejection (dB) It specifies the amount of the rejection of the aliasing noise. If you set this value larger, the aliasing noise will be reduced, but the high frequency of the converted sound will be also reduced. * Sampling Rate It specifies a target frequency. The value range is from 11025 (11.025kHz) to 48000 (48kHz). Non-integer value is allowed. Sample Size... This command converts the sample size between 8-bit and 16-bit. Add Channel... This command converts a mono file into a stereo file, or converts a stereo file into a 4ch file by adding the silent channel. Delete Channel... This command converts a 4ch file into a stereo file, or converts a stereo file into a mono file by deleting the latter channel. Exchange Channels... This command swaps the channels of a file. Format Conversion... This command converts the file format between AIFF and SDII. There are some AIFF files which cannot be played in the HD Play mode of the CBX-D5/D3. If this is the case, convert the file by "Rewrite AIFF Header..." option. Please refer "8. Play Mode" for the HD Play mode. Quit This command closes any open windows and quits TWE. 3. Edit menu ------------ Undo The Undo command reverses the effect of your editing to restore the data to its previous state. After "Undo" is used, it functions as "Redo". "Redo" will re- execute the editing operation that was undone by "Undo". Cut This command cuts the region and places it in the TWE clipboard. The sound data after the region is moved forward to fill the gap. This command is available only when all channels are selected. Copy This command copies the selected region, and places it in the TWE clipboard. Paste This command pastes the clipboard contents onto the sound data, starting at the beginning of the region. Insert This command deletes the region and inserts the clipboard contents. Clear This command cut the region without placing it in the clipboard. This command is available only when all channels are selected. Select All This command set the start and the end point of the region to the start and the end point of the sound file without changing the selected channels. Trim This command leaves the region and cuts the remainder. This command does not affect the data in the clipboard. This command is available only when all channels are selected. Mix This command mixes the contents of the clipboard with the sound data starting at the beginning of the region. Reverse This command reverses the time of the region. Invert This command inverts the polarity of the region. Fade In This command creates a fade-in starting from the beginning of the region and ending at the end of the region. Fade Out This command creates a fade-out starting from the beginning of the region and ending at the end of the region. EQ... (Equalizer) This command applies three band parametric equalizer to the region. Select the button for the frequency area for which you wish to apply the equalizer, and use the mouse to select a numerical value, then input the desired value from the keyboard. You may move the mouse to change the frequency response curve. By default, all three bands are set to the presence filter, but by entering the zero in the Q, the Low and High filter can be changed to the shelving type. Time Comp/Exp... (Time compression/expansion) This command changes the length of the region without affecting the pitch. This command is available only when all channels are selected. Pitch Shift... This command changes the pitch of the region without affecting the length. Gain... This command changes the overall amplitude of the sound data. Normalize... This command expands the amplitude of the region so that the peak value reaches the specified rate to the maximum value. Silence This command sets the region to silence. 4. Window menu -------------- The Window menu lists up all available windows so that you can select any window at once. 5. Setup menu ------------- The Setup menu contains commands related to setting up the environments for recording, playing back and editing. SCSI Rescan The SCSI Rescan command makes TWE acknowledge all devices currently connected to the SCSI bus. The results of rescan are displayed at the end of the Setup menu, as shown below. You can choose the hardware to record/play. (*) Downloading the firmware to CBX-D3. CBX-D3 needs the firmware to be downloaded. TWE downloads the firmware when it starts or "SCSI Rescan" command is selected. Hardware Set Up... This command lets you to set up the CBX-D5/D3. Select Working Volume... When you use TWE, various auxiliary files are automatically created for each sound file. These auxiliary files are used to hold the results of commands such as Copy/Paste or Undo, or as temporary memory. The Select Working Volume command specifies where these auxiliary files are created. Note: These auxiliary files are temporary, and disappear when you finish editing a sound file. However, if the system crashes or quits unexpectedly, or if some other error occurs, the auxiliary files may sometimes remain as the hidden files. When TWE is launched next time, it erases these remaining temporary files automatically. When selecting the Working Volume, make sure that you select a hard disk with sufficient free area and fast access. (Since creating a temporary sound file requires the same amount of space as the original sound file, you will need a minimum of approximately twice the size of the original sound file.) File Backup This command switches the edit mode between the original mode in which you edit an original file and the back up mode in which you edit a new copy of an original file. Recording Monitor This command switches the monitoring function of the input signal. When unchecked, monitoring is available only during recording. 6. Main window -------------- These two buttons perform the same functions as the Open and New commands in the File menu. 7. Wave window -------------- By the Open or New commands, a Wave window like the one shown below opens. You may open as many Wave windows as memory permits, and you can also open two or more windows for a single file. In this case, when a file is edited in one window, the results of the editing are reflected in the other windows. File information indicator This area displays the following information about the sound file. Creator : The creator of the file Samples : The total number of samples Length : The overall playback time Modified : The last modified date File type : The file type Sample rate: The sample rate in Hz Sample size: The sample size in bits Channel : The number of channels Data size : The size of the data fork of the file Display resolution indicator This indicates the resolution with which the time (horizontal) axis and amplitude (vertical) axis of the waveform are displayed. The time (horizontal) axis resolution indicates the number of samples per pixel. To modify the setting, select the number with the mouse and enter the desired setting from the keyboard. The amplitude (vertical) axis resolution indicates the sample value per pixel. The setting can be modified in the same way as for the time axis, by selecting the number with the mouse and entering the desired setting from the keyboard. Playback controls The playback controls allow you to record and playback the sound data. The function of each button is as follows. Set the Region to "From 0 to 0". Stop playback or recording. Start playback from the beginning of the region. Regardless of the channel selection of the region, all channels are played back. The selection of the region will be nullified afterwards. Start recording from the region location, and will continue until the end of the data is reached. You can click the above button to playback only the selected region. Volume indicator Here you can specify the playback volume. It is not possible to specify volume independently for each channel of the stereo or 4ch file. View region indicator This indicates the region of the waveform that is displayed in the Wave window. The start point, the end point and the length are indicated both as samples and time. You can input values in either Sample or Time, and the other setting will change to reflect the value you specify. The length will automatically be adjusted when you drag the grow box to change the size of the window. Please be aware that the view region indicator simply indicates the length from the beginning to the end of the waveform that is currently in view. Modifying this number will not expand or contract the waveform. If you modify the "From" value, the waveform will be displayed for the area starting at "From" and ending at the length specified by "Length". (The "To" setting will change automatically.) In the same way, if you modify the "To" value, the "From " setting will change so that the "Length" remains the same, etc. If you scroll the waveform display, the view region indicator will change to reflect the newly displayed data. Region select indicator This indicates the area of the selected region. The start point, the end point and the length of the area are indicated both as samples and time. You can input values in any box, and the other settings will change to reflect the value you specify. When you input a value in Samples or in Time, the other display will be recalculated automatically. You can also use the mouse to drag directly over the waveform display area for the same result. The values you input here are in units of 1 sample, regardless of the specified displayed resolution. Waveform display area The waveform display area displays the waveform of the sound data. Use the horizontal and vertical scroll bars to move the displayed area. You can use the grow box located at the lower right of the window to adjust the window size. The Display Resolution setting lets you set the resolution of the time (horizontal) axis in units of 1 sample per pixel. A setting of 0.5 means that each sample is displayed two pixels wide. The amplitude (vertical) axis is maintained internally as 256 steps from -128 to +127. This means that if you set the resolution to 1 or less, each of these 256 steps will simply be displayed larger. When using the mouse to select a region, the size of the selection will always be in units of the number of samples you specify for the Display Resolution. If you wish to use smaller (more detailed) steps for your selection, you must either set the Display Resolution to a finer setting, or directly input numerical values into the Region Select Indicator. When you click the mouse once in the waveform display, the region that was selected up to that time is deselected, and the cursor moves to the spot where you clicked. For a stereo or 4ch file, the window is split horizontally so that all channels are displayed in parallel. You may select regions either for an individual channel or for adjacent channels. To select two or more adjacent channels, drag the mouse across the divisions between channels. (See the illustrations below.) Some commands which modify the length of the data (such as Cut) are available only if all channels are selected.

Play mode ------------ HD Play Mode In this mode, sound data does not go through Macintosh. CBX-D5/D3 access to the HD directly. At the time of the TWE's first release, CBX-D5 supports this mode only. In this mode, you may find problem in recording/play back in the situation described below: * Some of HD utility software, which compresses the file to increase the disk space, is used. * When the stereo AIFF file, created by another application software, has the 2 (2n + 1) byte of header. (n = any integer) * When Macintosh has more than one SCSI buses and CBX-D5/D3 and the sound file are located on the different buses. * The sound file is located on HD connected to IDE bus. RAM Play Mode When playing back in this mode, the sound data is read from HD into the Macintosh's RAM, then it gets sent to the CBX-D3. When recording, the sound data is read from CBX-D3 into the Macintosh's RAM, then it is written to the HD. CBX-D3 supports both HD Play Mode and RAM Play Mode. By using the Macintosh's RAM as the buffer, CBX-D3 can get around the problems described above. One drawback of this mode is that the data traffic on the SCSI bus will be heavier. If you are playing 4ch file with a slow access HD, it may not work. ***************************************************************** NOTE-The TWE Manual file is quite large, so you may need to increase the memory allocation for TeachText/SimpleText. You'll know when there's not enough memory because some graphics will not be displayed, probably those at the end of the file. To increase TeachText's memory allocation, quit TeachText, then select the TeachText icon and choose Get Info from the file menu. In the dialog box, set the Preferred Size to at least 250k, close the dialog box, then re-launch TeachText. *****************************************************************
