OLD REW OS X DMG (includes private Java 8 JRE) V5.19 beta 8

Changes in beta 8:

• Reduced waterfall controls width to help formatting on low resolution screens
• Added a View preference to show or hide the toolbar, hiding it makes more space on low resolution screens
• Added a welcome message on startup with pointers to initial steps
• RTA graph images captured with distortion panel showing also include the RMS level panel
• Added 50 Hz as a 1/3 octave step for RT60 and Filtered IR
• Added new controls for the filter frequency on the Filtered IR graph, with selection boxes to enable and next and previous buttons
• Added support for 32-bit and 64-bit float PCM data when importing impulse, audio and sweep files
• Added 352.8k and 384k sample rate options for filter IR export and append sample rate to default filename
• If a WAV file being imported has two channels label them left and right rather than 1 and 2
• Allow 192k sample rate with Java drivers on Linux
  
• Bug fix: Predicted phase did not update when changing impulse t=0 offset
• Bug fix: Import audio files did not work for mono WAV files
• Bug fix: When an FDW was being applied phase response was incorrect if win ref time was not 0
• Bug fix: When using a USB mic and ASIO4All there could be multiple requests for the mic cal file on startup if the cal file did not have a sensitivity figure
• Bug fix: Exporting an impulse response that had only a short non-zero portion could result in a file that was all zero valued
• Bug fix: Import sweep recordings could give incorrect results if the current REW soundcard sample rate was less than the WAV sample rate
• Bug fix: Don't disable the output channel selector when output selection is not available

As beta 7 with fix for minimum phase generation not working.

Quite a few changes in this beta version, I'll list them here and make further posts to explain the changes.

• Added ability to import sweep recordings and generate measurements from them
• Added sweep level, timing ref level and sample rate selection when saving measurement sweep to WAV file
• Added sweep settings information into measurement sweep files saved as WAV
  
• Added option to capture spectrum data when making stepped sine measurements, the data can be viewed on waterfall and spectrogram plots
• Use FFT bin frequencies in stepped sine measurement
  
• Added 88.2k and 96k sample rates when using Java drivers. Make sure the input and output devices are
  configured in the OS to operate at the rate selected in REW, otherwise the OS will resample between the
  selected rate and the rate at which the input or output device is actually running.
  
• Added a menu entry to import audio data files for analysis
  
• Adjusted frequency-dependent windowing filter characteristics to improve wavelet spectrogram resolution
• Added linear amplitude scale settings for spectrograms (percent of peak or percent of full scale) and a percent full scale log setting
• Increased time axis resolution of spectrogram plots
• Revised the spectrogram time span controls to have separate controls for the spans before and after the IR peak
• Added a frequency axis selector to spectrogram to allow frequency to be on the X or Y axis
• Added a Fill spectrogram floor control, when selected REW uses the bottom of the spectrogram colour scheme to fill areas that have levels below the floor of the graph
• Added peak energy time as a separate trace on the spectrogram graph with time values in the graph legend
• Added window type selector in spectrogram controls and, for imported audio data, in waterfall controls
• The Y axis zoom out button on the spectrogram graph automatically limits to the full span of the spectrogram
• Added option to use colour bands in spectrogram
  
• Allow up to 501 slices in the waterfall - note that using more slices will increase memory use and the time taken to generate waterfall plots
• Added a spectrogram-style colour scheme option to the waterfall plot for graduated colours
• Made the cursor frequency line drawn over the surface of the waterfall more visible
• Updated the waterfall help for CSD mode to warn that window width should be greater than time range
  
• When using ASIO automatically reload the ASIO driver after the sample rate is changed
• Added A and C weighted input level figures on the RTA
• Added FBQ1000 as new name for DSP1124P
• Allow up to 35 m room dimensions for room simulator and modal analysis
• Additional input level check during SPL calibration to try and prevent incorrect calibration results
• Trace arithmetic treats inputs as incoherent if they do not both have phase data
• Reintroduced file overwrite check on OS X as OS no longer performs it
• Revised trace colour defaults
• Added a "separate traces" button for the All SPL graph
• Added units labels to the graph limits dialog
• No longer show measurement notes in tooltip for overlay graph legend selectors (gets in the way)
• Moved Measure menu entry into the Tools menu
• Added an Import sub-menu in the File menu
• Made the graph cursor easier to see, especially on high resolution screens
• State of measurement panel expand/collapse button is remembered for next startup; default for screens of 1200 pixels or less is collapsed
• Default for showing graph scroll bars on screens of 1200 pixels or less is not to show them
  
• Bug fix: 5.19 beta versions 4 to 6 were not compatible with Java 7 (used a Java 8 method)
• Bug fix: Spectrogram contour interval was not remembered for next startup
• Bug fix: Soundcard cal could fail to complete if measurement sweep had been set to a length above 256k
• Bug fix: Traces with colours that changed along the trace were not rendered correctly on retina macs

Changes in beta 6:

• Play a minimum level sine wave before the sweep starts to help with signal lock for digital connections e.g. HDMI
• Capture the noise floor before sweep and stepped sine measurements
• Added option to mask distortion harmonics that are below the noise floor (on by default)
• Show harmonics used in THD calculation in trace name
• When saving filter coefficients to file for Generic equaliser only include enabled filters
• Faster operation of the right click menu items in the overlay legend panels (trace selections)
• Improved visibility of data panels and some other elements when using dark colour scheme
• Bug fix: some component fonts were the wrong size
• Bug fix: export distortion data dialog would not appear for measurements made with earlier versions of REW
• Bug fix: Clarity values were not automatically calculated when viewing measurements with RT60 data generated before clarity calculation was added
