Assempix - Decode COFDMTV vs Chubby Click - Metronome
Side-by-side comparison of two open source alternatives
Assempix - Decode COFDMTV
*Assempix* decodes COFDMTV encoded audio signals to images and is based on open-source software.COFDMTV is based on COFDM (coded orthogonal frequency-division multiplexing) technology:- 160 ms long OFDM symbols- 6.25 Hz per sub-carrier- 1/8 guard interval- differentially encoded PSK (phase-shift keying) modulation- systematic polar codes for forward error correctionFollowing modes are supported:Using SPC(64800, 43072):Mode 6: 8PSK, 2700 Hz BW and about 10 seconds longMode 7: 8PSK, 2500 Hz BW and about 11 seconds longMode 8: QPSK, 2500 Hz BW and about 16 seconds longMode 9: QPSK, 2250 Hz BW and about 18 seconds longUsing SPC(64512, 43072):Mode 10: 8PSK, 3200 Hz BW and about 9 seconds longMode 11: 8PSK, 2400 Hz BW and about 11 seconds longMode 12: QPSK, 2400 Hz BW and about 16 seconds longMode 13: QPSK, 1600 Hz BW and about 24 seconds longPayload must be smaller or equal to 5380 bytes.JPEG, PNG and WebP image formats are supported.Width and height are limited to between 16 and 1024 pixels.
Chubby Click - Metronome
NOTE: The app is no longer developed. Chubby Click is a metronome designed for the musician that needs to easily manage a setlist of songs. The app features three sections: * A conventional metronome with tap tempo * A Setlist where songs can be added and sorted, and where the click for each song can be started/stopped with a single tap * A Practice section where metronome can be programmed to automatically increase/decrease BPM over time * Each beat in a bar can be accented or muted Setlists can be exported and imported. Sound (notes pitch and duration) can be customized and two presets are provided. The metronome can be controlled using media buttons on an external device (e.g. Bluetooth headphones).
