Hi,

hat jemand die neuste Beta vom REW und kann sie per Mail verschicken?

[kasbc]

Hallo Torsten,

wenn heute abend reicht (hab deine Mailadresse nicht da). Wenn du mir ne PM mit der Mailadresse schickst, kann ich aber auch gleich.

Gruß

[Sleepwalker]

Ist angekommen! :yahoo:Dat ging ja mal schnell!

Danke!

Tja, Service ist mein Business ... :rolleyes:

Was ist denn so besonderes an der neuen Beta, außer das das Ding nicht unter Linux läuft?

[kasbc]

The beta release of V5.01, Windows only for now, is now available for download. Use the "Drivers" selection box at the top left of the Soundcard preferences to select ASIO then choose the ASIO device, input and output. For most reliable measurements use normal or high latency settings on the ASIO driver.

Changes in this release:


Added support for ASIO drivers on Windows
Updated help to add All SPL graph to GraphPanel help
Tried a tweak to have the big-endian output flag default to on for OS X PowerPC platforms
Stimulus trace on scope plot is shown at level sweep was made at rather than 100 % FS
Added sample width selector for dither control on sig gen sine wave generator
Changed VU meter labelling to show "In" and "Ref In" for input meters with actual input name/channel in tooltip
Show an error message if user attempts to load an mdat file as a mic/meter or soundcard cal file
Allow ";" as line comment indicator for imported ASCII files (used by SMAART)
Added a check on soundcard calibration measurements to warn if measurement appears invalid
Added impulse response export options to export windowed response or minimum phase response
Added a warning message after SPL meter calibration if the input level was below -50 dB FS
Added a MiniDSP-96k equaliser option for 96kHz MiniDSP plug-ins (e.g. for 2x8)
Added parallel equivalent impedance display for impedance traces
Bug fix: TS parameters calculation could fail for some measurements
Bug fix: Problem opening EQ panel with a measurement generated from Trace Arithmetic
Bug fix: Target trace in EQ window did not include house curve when there were no measurements loaded
Bug fix: Do not use physical fonts unless default Locale language is en to avoid undisplayable characters
Bug fix: Export RT60 data as text was broken
Bug fix: Fill filter traces filled the house curve section of the target if a house curve was loaded
Bug fix: Force use of decimal point as decimal delimiter in SPL meter SPL value
Bug fix: Adjusted DCX2496 centre frequencies
Bug fix: Error when trying to upload TMREQ filters from surround or surround back channels
Bug fix: Exporting filter impulse response as WAV always exported the set from the currently selected measurement regardless of the selection made in the export dialog
Bug fix: Path to last imported impulse response was not saved correctly on exit
Bug fix: Hilbert transform had an error that affected envelope calculation


Beta 2 changes:

Bug fix: EQ progress popup did not stay on top of the EQ window
Bug fix: Could get LineUnavailableException on start up after using ASIO drivers


Beta 3 changes:

Warn user if ASIO buffer length not a power of 2 and disable multiple sweeps
Allow for ASIO driver reset, resync or buffer size change while REW is running
Suppress ASIO error on shutdown
Bug Fix: SPL Meter could give "input not available" error on start up after using ASIO drivers


Beta 4 changes:

Removed requirement for ASIO buffer length to be a power of 2 for multiple sweeps


Beta 5 changes:

Increased internal buffering for ASIO data
If RTA was running before starting a measurement, measurement would fail
Only warn about input overrun if measurement result could be affected
Bug fix: Could get poor quality impulse responses from 88.2k or 96k measurements


Beta 6 changes:

Made ASIO input buffering more efficient
Bug Fix: Ohms scale appeared on RHS of SPL overlay even with no impedance measurements loaded
Bug fix: Possible fix for corruption of EQ window when automatically setting filters


Beta 7 changes:

Revised calculation windowing for sweeps that do not start at 0
Bug fix: When using multiple sweeps with Java drivers only a single sweep was generated

Moin,

die neue Version beinhaltet einige neue, imo nützliche features.
So kann man jetzt mehrere Messungen in einem Plot sehen, Mini-DSP wird unterstützt (was ganz nett ist, denn REW wirft die Koeffizienten für die Biquads aus) und kann so automatisch gemessene Frequenzgänge "glatt" ziehen.
Auch für Falter gibts was neues, nämlich neue Filter (HPQ,LPQ) bei denen man die Güte (Q) einstellen kann, und Allpässe. Die Impulsantworten können wie gewohnt exportiert werden und als minimalphasige Filter genutzt werden.
Dass das Plugin für den MiniDSP nur die Koeffizientenn liefert, lässt vermuten das es die Software (Plugins) des MiniDSP auch so macht. Damit könnte man also auch "fremde" IIR-Filter füttern und bedienen ;)

Soweit ich das Blicke, sind das aber alles Funktionen, die auch in der normalen V5.0 schon drin sind.

In meiner 5.0 waren die nicht drin. Es gab kein MiniDSP usw...:confused:

[The Alchemist]

Dann war es wohl eine der unzähligen Betas...:D, ich hatte mir schon Sorgen gemacht, ich hätte was verpasst.

REW v5.01 Beta 10 Released

Beta 10 changes are as follows (uploaded 12/15/12):

On Windows REW automatically detects the MiniDSP UMIK-1 USB mic, offers to use it for measurement and prompts to load the cal file.
If the USB mic is selected sample rate is set to the preferred value for the mic (48k), capture volume control is set to 0.1 (for no gain), the Mic/Meter settings are set to mic input, use of other channel as a timing ref is turned off and the SPL readings are calibrated for the mic sensitivity.
Improved the waterfall controls to provide better control over appearance and frequency resolution and allow waterfalls to be used for examination of driver and cabinet resonances on full range measurements (see the Waterfall graph help in REW for details). Changes are:

Added a control to the waterfall plot to select the number of slices, up to 100 (previously fixed at 31)
Added controls to the waterfall and spectral decay plots to select the rise time of the left hand window
Added frequency and time axis markings to the floor of the waterfall plot
Added a control for the smoothing applied to waterfall and spectral decay plots
Added a control to the waterfall and spectral decay plots to operate in "CSD" mode, with the right hand end of the window remaining fixed rather than the whole window sliding along the impulse response.


Added a check box to show the modal frequencies for a room on a measurement, requires room dimensions to be entered via the EQ window
Added a control to the Impulse graph to shift the impulse by a time corresponding to an entered distance
When the impulse graph t=0 offset samples control is adjusted the time and distance offset controls update to show the equivalent values
Disable antialiasing when scrolling graphs to provide faster response to the controls
Disable antialiasing when adjusting waterfall x/y/z/slice sliders to provide faster response to the controls
Changed the input type selection in Mic/Meter preferences to clarify when the C weighted SPL meter should be selected
Added a file menu entry to export distortion data as text
Added CEA-2010 Tone Burst to the signal generator, to measure results use the RTA with FFT Length 65536 for 44.1k or 48k, 131072 for 88.2k or 96k, Rectangular window
For DSP-30 increased Q resolution to 0.01, max filters to 20
SPL calibration takes into account adjustments of input volume control (if accessible, i.e. input selected in REW, Java sound driver, running Windows)
Bug Fix: Changing ETC smoothing was still not working in locales using comma as decimal delimiter
Bug Fix: RT60 calc could reset an applied IR filter
Bug Fix: Square wave signal generator did not operate at sample rates above 48kHz
Bug Fix: Phase wraps in excess phase trace were not drawn dashed
Bug Fix: RTA one octave and half octave centre frequencies were wrong
Bug Fix: Filter selection check boxes on EQ filters panel were partially obscured
