- 4. _S_o_u_n_d__E_d_i_t_o_r
-
-
- Sound Editor (invoked from the command line as
- _s_o_u_n_d_e_d_i_t_o_r(1)) is a Motif application for recording and
- editing soundfiles that use AIFF format soundfiles.
- Although AIFF or AIFF-C files may be opened, all files are
- saved in uncompressed AIFF format. Use the _s_o_u_n_d_f_i_l_e_r
- utility to convert soundfiles in other formats to AIFF for
- use with Sound Editor.
-
- This program requires a Silicon Graphics system with digital
- audio hardware components (Iris Audio Processor) in order to
- capture and audition sounds. On systems without audio
- hardware, the record and play functions will be disabled,
- but soundfiles may still be viewed and edited.
-
- A graphical display of the audio stream data is presented
- for editing. Familiar word processor-style commands are
- available for manipulating the audio content. Sound segments
- can be cut, copied, pasted, or mixed by marking a region
- with the mouse and invoking the proper command. Additional
- functions are provided to modify levels and to perform fades
- and special effects.
-
- Sound Editor accepts a command line option, "-nofork", which
- will force the program to run in the foreground. Without
- this option, the standard behavior is for Sound Editor to
- fork and run in the background.
-
- Also, you may provide a soundfile name when invoking Sound
- Editor from the shell. This file, if it exists, will be
- loaded on startup. Otherwise, the file name will be used
- for a new file.
-
- You can customize the appearance of Sound Editor by altering
- its Motif application defaults file, _S_o_u_n_d_E_d_i_t_o_r, in the
- directory /_u_s_r/_l_i_b/_X_1_1/_a_p_p-_d_e_f_a_u_l_t_s.
-
- See your Motif/X11 documentation regarding use of the
- application defaults file.
-
- See the man page _s_o_u_n_d_e_d_i_t_o_r(1) and Sound Editor's on-line
- help for additional information about the tool.

- 4.1 _B_u_g__F_i_x_e_s
-
-
- The version of Sound Editor included in the Digital Media
- Tools 5.5 release includes the following bug fixes made
- since the 5.4 release.
-
- +o The file browser dialog box now returns to the last
- browsed directory when next invoked.
-
- +o The 'Trim' function has been reassigned a new
- accelerator key ('r') since the old one conflicted with
- the 'Cut' command ('t').
-
- +o Hitting the "Selection" button to zoom the waveform
- window to fit the current selection now accurately
- displays the full selection range.
-
- +o The selection time range correctly updates after
- hitting the arrow buttons to nudge the selection. Also,
- the played selection range now correctly matches the
- marked selection after using the arrow buttons to
- adjust the selection.
-
- +o The display field showing the cursor position (as text
- string) no longer flickers or disappears.
-
- +o The program now catches the window manager's close
- command when activated from the window's system menu.
- Previously, the program would exit without prompting
- for file save operation.
-
- +o There were situations where a saved file would be
- inadvertently removed when the program exited. This has
- been fixed.
-
- This section lists bugs which were fixed between the 5.2 and
- 5.3 releases.
-
- +o Files are correctly saved across file systems (multiple
- disk drives).
-
- +o Original file data no longer lost when saving to full
- disk.
-
- +o Waveform display clipping, overlapping and other
- artifacts have been fixed.
-
- +o Program will now run on machines without audio
- hardware.

-
- +o Program does not set hardware sample rates until user
- selects play or record.
-
- +o Program handles reading of hardware sample rates
- better.
-
- +o Program no longer dumps core when playing and scrolling
- the wave display.
-
- +o Fixed problem of file mask getting set improperly on
- save operations.
-
-
- 4.2 _C_h_a_n_g_e_s__a_n_d__A_d_d_i_t_i_o_n_s
-
- The version of Sound Editor included in the Digital Media
- Tools 5.5 release includes the following changes made since
- the 5.4 release.
-
- +o Before saving over an existing file, the program puts
- up a warning dialog and prompts the user to indicate
- that it's OK to replace the file.
-
- +o The type-in field for setting the amount of time in the
- waveform display has been replaced. Now there are two
- type-in fields which allow setting the selected range
- to a start and end time value (as a floating point
- value representing seconds). Use the "Zoom Selection"
- command to display this range if desired.
-
- +o Some menus have been rearranged to conform to the SGI
- Style Guide. The Options menu has been replaced with a
- Settings menu which contains the Overdub Record toggle.
- A Utilities menu has been added which contains the
- command to launch the system Audio Control Panel. The
- File:About... menu command has been moved to
- Help:Product Information.
-
- +o The keyboard focus policy default has been changed. You
- will now need to click within a text field first to
- give focus for typing. This also means that you don't
- have to leave the cursor within the text field while
- continuing the type.
-
- +o The Delete and Backspace keys are no longer used as
- accelerators for the Edit:Delete command. This command
- must be invoked from the Edit menu.
-
- +o Animators or others working with the 24 frames-per-
- second film format may invoke the program with a
- display option: '-24fps'. This argument should be
-
-
-
-
-
-
-
-
-
-
-
- - 4 -
-
-
-
- typed prior to the filename command line option. This
- will cause the display of time to be divided into 24
- fps marks. Frames falling on a 16th frame boundary will
- be shown with an emphasized tick mark (16 frames/foot).
- Frame numbers are shown consecutively for the duration
- of the file. Type-in fields expect whole frame numbers
- as input, although fractional settings can be made by
- dragging the mouse to select a range.
-
-
- The version of Sound Editor included in IRIS Digital Media
- Tools 5.4 is the same as the version that was shipped with
- IRIS Digital Media Tools 5.3.
-
- This section lists changes/additions to Sound Editor between
- the 5.2 and 5.3 releases.
-
- +o Support for OSF/Motif compliant cut-and-paste and
- primary selection transfer has been implemented. You
- can now use these operations among multiple instances
- of Sound Editor and other applications which support
- the SGI Soundfile target.
-
- +o New effect functions added: Set Level and Set Pitch
- allows scaling the amplitude or frequency of a region
- to a specific ratio.
-
- +o File Save Selection function added to simplify saving
- selected regions into individual files.
-
- +o Program can open AIFF and AIFF-C format soundfiles. 8,
- 16 and 24 bit sample widths are all acceptable. All
- files are saved in uncompressed AIFF format.
-
- +o File Insert command allows files of differing sample
- bit-widths to be inserted. Sample rate and number of
- channels must still match, however.
-
-
- 4.3 _K_n_o_w_n__P_r_o_b_l_e_m_s__a_n_d__W_o_r_k_a_r_o_u_n_d_s
-
- This section lists problems in Sound Editor and ways to work
- around them.
-
- +o Under certain conditions, the keyboard accelerators can
- become disabled. Bringing up the menu containing the
- desired command usually corrects this situation.
-
- +o Although the program can open either AIFF or AIFF-C
- files, there is no way within Sound Editor to export
- files in a particular format. Use the _s_o_u_n_d_f_i_l_e_r
-
-

-
- utility program to convert a file to another format.
-
- +o The cut-and-paste operations do not work correctly
- between different host machines. To work around this,
- copy all files to be edited to the same host.
-
- +o When altering the selected region during repeat play,
- it is possible for the play region to lag behind the
- user's input or sometimes play material outside the
- marked region. This behavior normally corrects itself
- after cycling through the marked play region.
