File Menu

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.
Open Measurement Ctrl+O
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.
Open Filters Ctrl+Alt+O
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 Frequency Response Ctrl+I
Import frequency response data (SPL or impedance) from other applications or load FR 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 Impedance Measurement Ctrl+Alt+I
Import impedance measurement data from other applications 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, an AIFF 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 and AIFF files can be mono, stereo or multi-channel, the channel to be imported is chosen when loading the file. Only Signed PCM 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.

Export -> Measurement as text
Export the measured data for the current channel as a text file. A note can be entered that is displayed when the data set is next loaded. The file includes the speaker setting, target level and measurement settings for the channel. These text files can be re-loaded using Import Measured Data. The path to the file is remembered for the next time the dialogue appears. An example of the format is shown below, it is compatible with the .FRD format. Comment lines start with *, data lines begin with the frequency, then the SPL in dB and finally the phase in degrees (0.0 if the measurement does not have phase information)
