Idea for new standard

Post by vladimirovich »


you are doing great job! Thank you!

Anyway, there are some ideas. They are mainly for format, I think that it's still possible to create 2.0 version of phonopaper.

1. Implement log scale for volume, it's better than linear one.
2. Implement pre-filter (and inverse post-filter) for phonopaper standard. Main Idea is analyzing typcal histogram of music or voise. Generally, low frequencies in every typical sygnal are more loud, so it's good idea to prefilter low freq before printing and postfilter them after decoding.
3. Implement dashed lines for exact time ticks (ex, every 0,5 sec line should do a little break).
4. Implement version with color coding
