& &&&由于入了小炮，一直在为摆位发愁，近日发现很多朋友都在使用一款叫作REW的免费测试软件。我也拿来研究了两天，但发现这款软真不是常人能玩的转的，在加上全英文界面，两天的时间下来，连最基本的声卡设置都没弄懂，更别提以后的那些图谱了，估计也要有一些专业知识才能看得明白。
& && &今发此贴我是想了解下REW这款软件到底是做什么的？对于我这种只有一部电脑、一支廉价麦克风的玩家来说，费尽心思去研究REW真得有意义吗？REW能够指引我找出最佳的低音炮摆位吗？
& & 如果说软件本身，只是让我去了解下房间的声音特性，而并不能改变我目前糟糕的状况，我......宁愿放弃了.....
& && & 请指点我！！！

U listen, U look, U're There!
很多以英语为母语的人都觉得REW有条很陡的学习曲线（就是起手很难的意思），你如果不是技术背景出身，我觉得你可以放弃了。
另外，如果你只愿意付很廉价又没有校准文件的麦克风这点代价，即使你学会了如何使用REW，测试结果也不会很准确。一套可以一用的REW配套设备价格在100到150美元左右。
最后，即使你有了设备和学会了测量，你还需要相应的知识解读测试数据并能加以利用。这就象noheart兄所说，需要你把这件事当作乐趣来做。否则，还是算了吧。
但好处是：你可以发挥器材的最好效果，而不是走向唯器材价格论这条道路。

正准备今天开始研究这个软件呢，看到这个帖，有点吓人啊……
不过还是要试试REW，器材已经不想再折腾了，学习一些理论知识、软件应用，又是另一种乐趣，且更理性一点，也有更多的可交流的“料”，而不是一见面就是——我的音箱是XX牌子XX价格的，说完这些就没什么可交流的，实在是无趣。

rew我觉得不怎么难！测试mic之类每一步都有解释的！
我目前还只用到最基本的扫频功能，但是已经为我找到炮位提供了极大的方便！在同一个位置，炮口对不同方位都能带来不同的曲线，炮上相位的调整也可以实时看到！

Powered byV5.19 beta 12 9th August 2018
Improved rendering of text on spectrogram graph images when spectrogram floor is filled
Small refinement to the IR start detection code
Changed delay figure with acoustic timing reference back to using IR start time for limited bandwidth measurements (e.g. subwoofers), retained use of the Estimate IR Delay process otherwise
Bug fix: Added checks to try and prevent occasional exception when opening the EQ windowAdded Leq traces for the last minute and the last 10 minutes to the SPL logger
miniDSP UMIK-1 calibrated USB measurement microphone
Dayton Audio EMM-6 calibrated analog measurement microphone
Steinberg UR22 MkII USB audio interface
Focusrite Scarlett Solo USB audio interface
miniDSP 2x4 HD DSP / Equaliser / USB DAC / crossover
V5.19 beta 11 21st July 2018
Added Leq traces for the last minute and the last 10 minutes to the SPL logger
Added * in front of comment lines in the impulse response text export file and a * Data start comment immediately before the data
Trim trailing zeroes when exporting impulse response as text with window applied, but note that the data will be padded with zeroes so the length is a binary power if required
Show an error message if the file selected for data import does not have any data REW can read
Reset the file filter list before setting a new filter to prevent filters accumulating in the list of available filters
The currently selected input is shown in the title of the RTA window
Bug fix: If the previously selected input device was no longer available on startup (showing blank in the Soundcard preferences) high CPU usage would occur when attempting to capture audio
Bug fix: SPL meter decay rates were too fast
Bug fix: Signal generator saving to WAV file could have incorrect frequencies if the chosen sample rate differed from the current REW sample rate
Bug fix: Measurement sweep was 3 dB higher than selected if the View option "Full scale sine rms is 0 dBFS" was selected
Bug fix: On macOS REW would quit even if Cancel was selected on the unsaved measurement dialog
Bug fix: The height of captured graph images was wrong if the selected image width didn't match the default width
V5.19 beta 10 15th July 2018
24-bit data is now supported where the JVM makes it available (currently macOS and probably Linux)
Added 176.4, 352.8 and 384 kHz to the sample rates allowed for ASIO
Allow generator to continue running if ASIO output selection is changed - audio will be interrupted briefly, however
Added a dBc axis option for the RTA (dB relative to carrier, mainly used to present data relative to the level of the fundamental tone in the signal)
Only stop the generator after SPL calibration if the generator was started by REW
Added a colour scheme for spectrograms and waterfalls based on Dave Green's cubehelix, see https://www.mrao.cam.ac.uk/~dag/CUBEHELIX/
The delay figure with acoustic timing reference now uses the Estimate IR Delay process (cross correlation with minimum phase response) for better results with measurements that do not have HF content (mids or woofers)
Added warning to check mic access is allowed in Windows Privacy settings if input is not accessible
Added an option to allow/disallow narrow filters below 200 Hz when matching to target
Added an option to use IEC263 25 dB/decade aspect ratio when capturing graph images
Changed graph image capture to render the graph directly at the chosen width rather than scaling from the current width
Added a Tone Burst option to the signal generator
The Nimbus look and feel places the file chooser focus on the directory selector instead of the file name field, added a workaround for that
Added options to normalise, apply window and export min phase version to the export impulse response as text dialog
Updated the impedance measurement setup images to make it clearer that outputs and inputs are from the same device
Expanded the RT60 graph help
Bug fix: Aborting measurement for exceeding SPL limit should not apply to impedance measurements
Bug fix: Acoustic timing ref would be one channel out if using Java drivers with a multi-channel output and the ref output wasn't left or right
Bug fix: Spectrogram top level could get set to an incorrect value when changing measurements
Bug fix: Starting phase for signal generator linear or log sweeps was not reset to zero for each new sweep (did not affect measurement sweeps)
Bug fix: The level of custom filtered pink noise was affected by the low and high cut filter frequencies even if the filters were disabled
V5.19 beta 9 2nd April 2018
Added input selectors to the Measure dialog
Added a soundcard preferences control to set the mapping from REW's output channels to hardware output channels and choose the label to use for them
Multichannel output is no longer limited to 8 channels, allowing use of interfaces with higher channel counts on OS X (and probably Linux). The channel mapping control allows any 8 of the available output channels to be selected for use during measurement.
Devices with multichannel input are now supported on OS X (and probably Linux)
Added two protection mechanisms for sweep measurements, abort if excessive input clipping detected or if an SPL limit is exceeded. Both are controlled on the Measure dialog.
Added two protection mechanisms for the signal generator, stop if excessive input clipping detected or if an input SPL limit is exceeded.
Added an option to stop stepped sine measurement if excessive input clipping occurs
Added sample rate and channel selections for the signal generator WAV file export
Altered TS parameters optimisation to improve fitting. Data above 10 kHz is now not used for fit.
Show input name in title of SPL Logger window
When saving RTA data as measurement can now create measurements from current values, peak values or both (previously measurements were created from current values only)

Bug fix: Update input name in SPL Meter title when input selection changes
Bug fix: Distortion noise floor was not lowered when using multiple sweeps to reflect the theoretical improvement obtained (3 dB for each doubling of number of sweeps)
Bug fix: ASIO input could time out after changing ASIO output
V5.19 beta 8 14th January 2018
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 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
V5.19 beta 7 1st October 2017
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

Bug fix: Impedance measurements can sometimes be affected by an inter-channel timing difference, possibly related to running the card at a different rate to the REW rate. If a timing difference of 1 sample or less occurs REW compensates for it, if more than 1 sample a warning is shown.
V5.17 beta 8 10th August 2016
If a USB mic is selected without having a cal file with sensitivity data loaded the SPL calibration status is cleared
If SPL calibration is attempted with a USB mic selected that doesn't have sensitivity data ask for the mic cal file

Bug fix: With ASIO drivers the timing ref output selector was shown when first opening the measurement dialog even when not using a timing reference
Bug fix: RTA and Spectrum traces were drawn 3 dB lower than they should be when the axis was set to dBFS and the View option for "Full scale sine rms is 0 dBFS" was selected
V5.17 beta 5 2nd July 2016
Modified RT60 calculation to cope with responses that have been truncated before they reach the noise floor
V5.17 beta 4 2nd July 2016
Modified RT60 calculation to better cope with responses that have a large initial decay
Added a secondary output selector to the measurement dialog when using ASIO drivers
Bug fix: Schroeder trace on Filtered IR graph was not updated when filtering settings changed
V5.17 beta 3 27th June 2016
In distortion controls the options to limit norm. to 30 dB below peak and to use harmonic frequency as ref are only enabled when plotting normalised to fundamental as otherwise they have no effect
Removed 10 Hz lower limit on white periodic noise
Added option to use 64-bit FFT processing on RTA when need to resolve below -160 dBFS, e.g. analysing 24-bit digital data paths
Adjusted dual tone f1 level to match the sig gen rms level setting (means clipping occurs if level is set higher than -9 dBFS for 1:1 signals or -6 dBFS for 4:1 signals)
Bug fix: RTA rms level and average count not shown in correct position (beta 1 bug)
Bug fix: Graph axis selector could disappear when trying to select from dropdown on OS X
V5.17 beta 2 1st June 2016
Bug fix: graph controls window was not displayed properly (beta 1 bug)
V5.17 beta 1 31st May 2016
Added delay info to measurement notes when using loopback or acoustic timing reference
Added buttons on the graph to quickly switch between two preset frequency spans that are defined in the View preferences
Increased precision of distance readout on zoom box
Bug fix: distortion data was not generated for first measurement after startup and was wrong for first measurement after changing sweep span
