Pokud to někoho zajímá a ještě o tom neví neví, je nová verze ARTA - v1.6.0

[godz]

Vďaka za info. Mateljan rozdával mikulášske darčeky. Cez víkend skúšam.

Dík za info, je tam něco nového, co by stálo za upgrade?

Nevím, nestudoval jsem to. Ale asi to bude ppsané na webu autora.

New features, implemented in program ARTA, are:
- Signal recorder now function as storage scope with triggering capabilities on both channels, with predelay and postdelay.
- For recorded signal the gated spectrum analysis and Short-Time Fourier waterfall plot are possible.
- Import from wav and ascii files can be analysed as IR or signal time record.
- A contour plot added for the presentation of directivity patterns.
- In reveberation window, the 95% cut of tail enabled.
- In all time windows 8 x zoom enabled, with zoom report on graphs.
- A button is added to Imp window control bar, for setting cursor on position of max amplitude.
- New tool: Two-channel voltage level meter and 1/3 oct. analyser.
- Enhanced FR target filter generation.
- Difference mode - in Fr1, Fr2, Spa - shows difference of Magnitude and overlay levels.

Following bugs are removed:
- Arta 'Load target' command - accept files with arbitrary number of points (removed hidden restriction on 720 points)
- Arta peak meter in SPL windows is tracking the peak in every recorded blocks
- Limp correctly reports Le.
- Steps correctly reports X-axis values in Distortion vs. excitation plot.

Potreboval by som radu. Meriam cez loopback zvukovku M-Audio Audiophile 2496. Pokiaľ viem, pri meraní THD by mali byť lepšie výsledky pri nastavení vyššej samplovacj frekvencie. Samozrejme za tej podmienky, že sú parametre správne nastavené /rovnako/ v Control paneli zvukovky a v nastavení Arty.
Prečo mi potom vychádza spektrum "čistejšie" pri 24/48 ako pri 24/96 ? Používam OS Vista 64. Dík za radu.
Tu je meranie pri 24/48:

ARTA version 1.6.1 is published (see download section).

New features, implemented in program ARTA, are:
- Saves background color in registry.
- IR measurement dialog gets check box 'Close after recording' to close itself after recording.
- Alt-R-R-R starts and closes measurement in PIR window.
- Alt-R-R starts and closes measurement of PIR in FR window.
- Envelope and Step response windows remember the zoom ratio.
- Shorcut keys for Cursor movement: Home (to 300 sample) , Del (to 0 sample).
- Shorcut keys for Cursor movement are: Crtl+Home (to 300) , Ctrl+Del (to 0), Ctrl+Ins (to cursor).
- Signal recorder can do a triggered time averaging.
- Spectrum estimation of gated recorded signal now gives an averaged spectrum of ovelapped segments.

Foollowing bugs are removed:
- Contour plot appears after reopening the directivity window.
- In correlation graph the background color now trace the global backgound color.
- Spectrum overlay does not depend on type of window (if made in PSD mode must be used in that mode).

Pokiaľ to neviete, je vonku ARTA version 1.7.0.
