3. Added dataset: crest_kurtosis.csv, Added example file: crest factor and kurtosis.mmj
4. Added CF (Crest Factor) display when using: Ctrl + Shift + Mouse Click + Drag & Drop selection
5. Added support for 24-bit/sample IEEE float format when loading audio files
6. Updated audio recording hotkeys: Start recording: F2 → Ctrl + R, Stop recording: Ctrl + R, Enter, or Space
7. [PROCESS Panel] Added tooltip for # of FFT setting in Spectra:
→ If # of FFT > 1000, automatic zero-padding is applied
→ If # of FFT > 1000, automatic 8-segmentation is applied
8. Updated model: Samples/order spectrum.mmj, Updated corresponding data file: vibration.dat
9. Fixed errors when loading certain MATLAB MAT-files
Update Details(2.5.0)
New features, performance improvements, and bug fixes to enhance stability and signal processing performance in MALMIJAL-M.
1.Expression Input Support for Numeric Fields
In non-integer numeric input fields, MALMIJAL-M now supports mathematical expressions, including basic arithmetic and common constants/functions such as pi, e, sin, cos, tan, abs, sqrt, exp, log, log10, and pow. After entry, the expression is automatically evaluated and converted into a numeric value.
Examples:
2*pi*1000 → 6283.185…
sqrt(2) → 1.414…
log10(1000) → 3
Invalid Expression Error Popup
2. Angle Option Added for Envelope Processing
An Angle checkbox has been added in the Preprocess tab when selecting Envelope Curve.
When enabled, MALMIJAL-M internally applies the Hilbert Transform to calculate the signal angle (phase) instead of the envelope curve.
For an example workflow, see:
“Samples/FM envelope.mmj”
3. Time Delay Added to Preprocess Tab
A Time Delay function has been added to the Preprocess tab, allowing users to shift signals in time for analysis and alignment purposes.
Example workflows can be found in:
“Samples/echo.mmj” and “Samples/detect delay.mmj”.
