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 โ Ctrl + R, Stop recording: Ctrl + R, Enter, or Space
7. [PROCESS Panel] Added tooltip for # of FFT setting in Spectra:
โ If # of FFT > 1000, automatic zero-padding is applied
โ If # of FFT > 1000, automatic 8-segmentation is applied
8. Updated model: Samples/order spectrum.mmj, ย Updated corresponding data file: vibration.dat

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 โ 6283.185โฆ
sqrt(2) โ 1.414โฆ
log10(1000) โ 3
Invalid Expression Error Popupย
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:
โSamples/FM envelope.mmjโ
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:
โSamples/echo.mmjโ and โSamples/detect delay.mmjโ.
