Measure spectrum to determine dominant in nanometers, frequency in terahertz, and period length in femtoseconds. Analyze sources to identify primary color wavelengths and associated properties.
The app generates Morse Code audio tests using common English words. Users can adjust speed and tone, with options to display or hide words for learning and practice.
Allows users to adjust and calibrate instrument pitches. Select frequency and tuning settings. Display pitch for each string indicating signal high or low. Calibrate piano sound using an open string. Adjust A4 frequency between 428 and 452.
Audiobus V3 plug-in for audio processing. Apply effects to enhance sonic clarity and natural frequency response. Adjust settings to refine sound without traditional equalization. Access demo version with limited free playtime.
Tune instruments with real tuning technology for pitch detection. View a bright, visible display in low light. Compare tuning accuracy against FFT-based tuners. Lock in pitch with a single tap. Sync with MIDI devices for real-time feedback.
Record audio from a microphone or external sound card. Process signals in real time with a dynamic . Apply non-linear filters and adjust settings through a functional user interface. Integrate as an AUv3 plug-in in compatible host apps.
Decode Morse code from microphone input. Practice sending codes and check accuracy. Adjust signal strength and speed for better decoding. Sync with 5-10 characters for accurate timing.
