This release introduces new features, performance enhancements, and bug fixes designed to improve the stability, usability, and signal processing performance of MALMIJAL-M.
1. [Work Model]
- Added "Import MMJ File" to the Work node context (right-click) menu.
Import result of the AM signal.mmj file under the Work1 model.
2. [Preprocess Panel]
Arithmetic Operation:
- Added support for dB Sum and dB Subtraction.
- Added support for using time-domain data and selected frequency-domain data (FFT, Power Spectrum, PSD, and Octave Band) as input to DATA and PROCESS operations.
Convolution:
- Full Option: Added a Full option to control the processing mode.
Checked: Use for frequency analysis
Unchecked: Use for filtering
Refer to Samples/convolution theorem.mmj for an example.
- Spectral Envelope
Added Spectral Envelope.
Applies envelope smoothing to FFT results using a Moving Average filter with a user-defined window size (order).
3. [Spectra Panel]
Octave Band Analysis
- Added the "Use Input as Octave Bands" checkbox.
- Use this option when the input data is Octave Band data instead of time-domain data.
4. [General Graphics Options]
- Added Left (←) and Right (→) arrow key navigation for the Data Cursor.
- When plotting multiple Octave Band analysis results together, you can now choose from three visualization types:
Grouped Bar Graph (default)
Transparent Bar Plot
Scatter Plot

- Added support for displaying Overall dB and dBA values.
