MusicMath vs AudioIQ

"MusicMath" is a musical tool that includes a timecode calculator, a tap tempo, a tempo to delay in milliseconds and hertz converter, a note to frequency table converter, a sample length converter, a tempo change converter, and a frequency to note converter. Timecode calculator: • Add and subtract timecodes or frames • Convert a number of frames to timecodes • Simultaneously convert the number of frames and the timecode • Conversion of timecode when changing the frame format • Managing frame formats 23.976 fps, 24 fps, 25 fps, 29.94 fps, 29.97 fps, 29.97 fps drop frame, 30 fps, 50 fps, 59.94 fps, 60 fps • Real-time display for formats 23.976 fps, 29.94 fps, 29.97 fps, 59.94 fps • Unlimited history calculations • History can be saved and exported to other applications Tap tempo: • Improved algorithm for impresize tap • Metronome • Transfer calculated tempo to other MusicMath tools Tempo to delay table: • Convert tempo to milliseconds and hertz • Convert for whole-note, half-note, quarter-note, eighth-note, sixteenth-note, thirty-note, and sixty-fourth-note for dotted notes and triplets Note to frequency table: • Convert MIDI notes to frequencies • Adjustable diapason and root note • One hundred selectable temperaments • Visualization of intervals in cents for each temperament • Taking into account the temperament for the calculation of frequencies • Plays piano sound when notes are touched Sample length converter: • Convert length between samples, milliseconds, and tempo Tempo change converter: • Calculates tempo change by ratio (%) and transposition Frequency to note converter: • Convert a frequency to the closest note and the cents needed • Plays the frequency

Audio IQ is ear training built for audio engineers. Instead of intervals and chords, you practice recognizing what actually matters in a mix: EQ moves, compression, distortion, reverb, delay, phase issues, limiting, saturation, loudness differences, and codec artifacts. Every exercise plays real recordings, never synthesized test tones, across dozens of genres — classical, jazz, military band, folk, world music, and more. ELEVEN MODULES EQ — spot the boosted or cut frequency band Compression — tell apart subtle, moderate, and hard-squashed dynamics Distortion — recognize overdrive, fuzz, digital clipping, and bitcrush Loudness — judge level differences by ear, in dB Reverb — tell room, hall, plate, and cathedral apart Delay — judge how long the echo repeats are Noise & Artifacts — spot hum, hiss, clicks, and pops Phase & Mono — hear a mix collapse in mono or cancel out of phase Limiting — feel the difference between compression and a brickwall ceiling Saturation — dial in warmth from clean to hot Codec Artifacts — recognize what a mix crushed to a low bitrate sounds like PRACTICE + LESSONS Every module has two modes: a multiple-choice Practice quiz to test yourself, and a free-play Lesson lab with live sliders so you can explore each effect at your own pace before or after quizzing. BUILT TO FIT YOUR LEVEL Set difficulty once in Settings — Beginner, Intermediate, or Advanced — and it applies everywhere, narrowing the gaps as you improve.
