"MusicMath" is a musical tool that includes a timecode calculator, a tap tempo, a tempo to delay in millisecond 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 frames format
• Managing frames 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

Release notes:
• Minor bugs fixed
