- Measure Ctrl+M
- Make a new measurement (brings up the measurement panel)
- Save Measurement Ctrl+S
- Save the current measurement in a binary format with the extension ".mdat".
The path to the file is remembered for the next time the dialogue appears.
- Load Measurement Ctrl+L
- Load a measurement from an mdat file. The path to the file is remembered
for the next time the dialogue appears.
- Save All Measurements Ctrl+Shift+S
- Save the data for all measurements in a single file with the
extension ".mdat". A note can be entered that is displayed when the
data set is next loaded. The path to the file is remembered for the
next time the dialogue appears.
- Save Filters Ctrl+Alt+S
- Saves the EQ filter settings for the current measurement in a binary
format with the extension ".req". A note can be entered that is
displayed when the filters are next loaded. The path to the file is
remembered for the next time the dialogue appears.
- Load Filters Ctrl+Alt+L
- Load a set of EQ filters for the current channel from a .req file.
Any note saved with the settings will be displayed. If the .req file has
more than one channel of filters a selection box is offered to choose the
channel to load the filters from.
- Import Measurement Ctrl+I
- Import data from other applications or load data which has been saved
in a text format. See
Importing Measurement Data for details.
The path to the file is remembered for the next time the dialogue appears.
- Import Impulse Response Ctrl+Shift+I
- Import an impulse response from a WAV file or a .pcm file (raw data)
as produced by ETF from Full Range measurements using the
File -> Write Impulse As *.pcm option. The sample rate must be
specified manually for .pcm files as it is not contained in the file
(ETF shows the sample rate in the pop-up which appears after exporting
the response). WAV files cam be mono, stereo or multi-channel, the channel
to be imported can be chosen when loading the file. Only Signed, little-endian
PCM WAV files are supported, with 16, 24 or 32 bit samples. To re-scale
the impulse response for a desired peak SPL figure in the frequency response
use the
Scale Response
controls in the Impulse graph group. The path to the file is remembered
for the next time the dialogue appears. N.B. Mic/Meter calibration,
soundcard calibration and C weighting compensation are not applied to
imported impulse responses.
- Export -> Impulse Response as WAV
- Export the impulse response for the current measurement in WAV
format, written as mono signed PCM data, with the impulse response
starting 2 samples into the file (the first 2 samples are zero). The
response length is 128k samples (131,072). The dialog provides options
to choose the number of bits per sample and to select whether or not
to normalise the response so that the peak value is unity (0dBFS).
32-bit sample width is recommended if the application using the data
can accept this, particularly if the response is not normalised.
- Export -> Filters Impulse Response as WAV
- Export the impulse response of the filters for the current measurement
in WAV format, written as mono signed PCM data, with the impulse response
starting 2 samples into the file (the first 2 samples are zero). The
response length is 128k samples (131,072). The dialog provides options
to choose the number of bits per sample and to select whether or not
to normalise the response so that the peak value is unity (0dBFS).
32-bit sample width is recommended if the application using the data
can accept this, particularly if the response is not normalised.
- Export -> Filter Settings as text
- Export EQ filter settings for the current measurement in a plain
text format. The file includes the speaker setting and target level
for the channel. This file is a convenience format only, REW cannot load
filter settings from text files - use the .req format to save and reload
settings. The path to the file is remembered for the next time the
dialogue appears. An example of the format is shown below.
