V1.2e - Slight improvement of TacTSpecial, Wav-Filter applies
triangular (TPDF) dither, removed LogSweep Recorder function from
Acourate due to introduction of the separate LogSweep Recorder acourateLSR
22.10.2006:
V1.2 - ASIO Logsweep Recorder introduced. You can now record the sweep
by Acourate itself (e.g. Audacity is no longer required). The recorder
is designed for the purpose of logsweep recording. The recorder uses
the ASIO interface to overcome some limitations of the Windows MMIO
system. Thus an ASIO driver is necessary with your soundcard. Most
soundcards have such a driver. If not (e.g. mainboard soundchips) then
try to run with ASIO4All, see http://www.asio4all.com/. The filename of
the recording is the logsweep filename with the ending _rec.wav.
16.10.2006:
V1.1 - TacT RCS2.0S and 2.2X supported. Workaround solution completely
outside of RCS measurement functions. Thus possibility to control the
correction result. Acourate generates crossovers as correction files.
Correction files also include these crossovers in mode 2.0.
19.09.2006:
V1.0d - small modifications to improve the user interface
18.09.2006:
V1.0b
- Target Designer. Starting with version 1.0 Acourate has a target
designer included. Easy creation of target curves without editing.
Select the appropriate drag operation and draw your target along the
measurement curve. Store a target and make a new one with slight
differences for listening comparison. Watch out for the next tutorial.
08.09.2006:
V0.7 - Room correction functions automated. Up to now Acourate has used
single functions to be called for each step. Starting with V0.7
Acourate has macros to allow easier computation of room correction
filters. The macros require some conventions are met. Licensed users
will recieve detailed information about utilizing the automation
functions. Shortcuts for functions introduced, see menu for description.
28.08.2006:
V0.6q - New function: Time Alignment Assistant. Now you can mark the
time alignment peaks and easily get the necessary delays, see tutorial
no. 4. Logsweep Generator: now creation of stereo left/right only
signals possible. Dirac test pulse can be added to logsweep to check
for time glitches between playback and recording. Save function: after
save the chart legend is updated to the save filename.
22.08.2006:
V0.6o - New menu: wav-Functions. The 1st function 'wav-Filter' allows
to read standard wav-files (16bit, 24bit, 32bit) and to apply one
(mono, stereo) or two different (stereo) filters, e.g. room correction
filters, on the wav-file. The result is stored under the same filename
with the extension _FIR.wav. The filter(s) have to be loaded as curve1
(and curve2). Processing time for a stereo wav-file of ~5min length
with two different filters of size 65536 taps on my laptop is about 10
seconds. The new function allows user to test or use a room correction
without a convolution engine by grabbing a CD, treating each track with
wav-Filter and burning the modified track on a CD.
15.08.2006:
V0.6n - Acourate now reads also mono 32bit wav-files. The LogSweep is
saved as 32bit wav-file, this allows to open it easily with Audacity.
The logsweep convolution also working with 32bit wav. Thus the export
format of Audacity should be set accordingly. Compression function:
frequency range selection added. Amplitude Difference also creates
minphase signals. CutNWindow: peaksymmetric checkbox visible again.
Radiobutton for marked area displays the selected range. Some minor bug
fixes.
07.08.2006: V0.6m - Added functionality to
CutNWindow with peak search in marked selection, FatLine Checkbox for
an easier identification of the active curve by a thicker line,
Samplerate 88200 Hz added, Samplerate Converter also handles 88200 Hz,
some more info in the Amplitude Chart
05.08.2006:
V0.6k - XP Manifest, Zoom button pictures, 96 kHz bug fix
21.07.2006:
V0.6f - Selection of right marker could create problems, bug fixed
19.97.2006:
V0.6e - Usability improvements: Introduction of Expert/Normal user mode
(ini-file), Logsweep convolution progress bar, Filename for Save,
Selection indication by colorband
17.07.2006: V0.6d
- raw-format for open allowed, Normalization refined, Save function for
all samples in full license refined, bugfix with step response display,
killed by a grue.
07.07.2006: BruteFIR on a USB
memorystick - added package ready to use for a RME HDSP9652 soundcard
including setup instruction.
07.07.2006: V0.6c -
Logsweep format changed to *.raw for better compatibility with
Audacity, convolution filename bug fix.
02.07.2006:
V0.6b - Improvement of AQT3 psychoacoustic, improvement of frequency
response marker selection
27.06.2006: V0.6a - New
functions: Leading/Trailing Zero Insertion, AQT3 Psychoacoustic
Frequency Response; Modification: SampleRateConverter with
KaiserImpulse instead RemezImpulse for stability reasons, Behaviour of
Function Form3
13.06.2006: V0.5e - Bugfixing -
always these little bugs :(
10.06.2006: V0.5a - New
functions: Samplerate Conversion, Logsweep Generator, LogSweep
Convolution (computation time for 2 x 60 sec logsweep and inverse in
double precision ~ 10 sec on my Centrino laptop), improved display
speed with millions of points, e.g. LogSweep measurement

Note: Please download together with new MtxVec build 16.5.06 -
26.05.2006:
V0.4a - New functions: Linear Phase Extraction, Group Normalization
24.05.2006:
V0.3g - Minor changes: display of computer ID, icon
22.05.2006:
V0.3e - First release of Acourate trial version at www.acourate.com
