FILE MENU 473
Timestamp: The timestamp saved in the BW (broadcast wave) extension is displayed here.
This is the timecode for recording the file, which is identical with the timecode of the first
recording if the recording was synchronous. For other applications, this timestamp
provides information about the time on the day of recording. The timestamp may be edited
or applied from the object position. You can assign the timestamp from the object
positions to all wave files.
Unique material Identifier (UMID): Handling of the UMID is regulated by SMPTE. An
corresponding document is available from SMPTE. The code number is SMPTE 300M-
2000. We recommend these reading the guidelines and agreements regarding the use of
the UMID before using this feature, which may be applied accorind to your needs. Use of
UMID is not absolutely necessary for a valid BWF.
Coding History: Besides information about the file format (A: encoding, e.g. PCM, F:
sample rate, W: bit width, these values are only used with non-transparently encoded
material like MPEG or MP3, M: number of channels), each entry of this field contains a T
value. This is a comma-free text string for entering serial numbers of recording tape
machines, codecs, dither types, AD converters, or special signal editing applied to the file
(like denoising).
An entry is made when a file is recorded in Samplitude. If this file is processed again (e.g.
the bit width has been reduced or via MPEG encoding), then an additional entry is added.
Use of this coding history is regulated by EBU recommendation R98-1999.
Broadcast Wave Manager - Advanced Options
Save BWF graphic data in wave files: If this option is activated, Samplitude creates a so-
called "peak chunk" that saves graphic information as a meta data in the file. Samplitude
usually saves graphic data in separate files (.ho files).
Read BWF graphic data and use data in Samplitude: If this option is activated, the peak
chunk included in a BW file is used instead of a .ho file.
CD Arrange Mode
If this is activated, Samplitude arranges recently added objects to insert a Red Book
Standard-compatible pause between the objects.
Detailed information about "CD arrange" mode is provided in "CD arrange mode (view
page 792)".
Destructive Wave Edit Mode
This menu item activates or deactivates the destructive editing mode in the wave project
window. If this point is deactivated, then Samplitude is put in "Virtual wave editing" mode.
Detailed information about destructive editing is available in the chapter "Working in the
project window -> Samplitude as a wave editor (view page 108)".
