- 22. _S_o_u_n_d__E_d_i_t_o_r__T_o_o_l
-
-
- 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 _m_e_d_i_a_c_o_n_v_e_r_t
- 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 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.

- 22.1 _B_u_g__F_i_x_e_s
-
-
- This section lists bugs which were fixed between the 6.2 and
- 6.5 releases.
-
- +o The program is now able to record sound files with a
- sample bit width equal to 24.
-
-
- 22.2 _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 IRIX 6.5 is the same
- as the version that was shipped with IRIX 6.3 and 6.4.
-
-
- 22.3 _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 Sometimes, if you paste sound data from another
- application into Sound Editor, the time-ruler may not
- get redrawn properly. If you force a redraw of the
- window by resizing it, the time-ruler will get updated
- properly.
-
- +o If all the audio ports are open, and Sound Editor
- cannot allocate an audio port, Sound Editor may crash.
-
- +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 _m_e_d_i_c_o_n_v_e_r_t
- 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.
