Are there any fast lossless 1-D signal compression algorithms out there which do a better job than, say, zlib for dealing with signals that are either a sequence of integers or floating-point numbers with common spectral properties? (usually band-limited) I need to compress a bunch of data, and uncompress it in Python, and it seems like the general-purpose data compression algorithms might be missing opportunities.

Blosc is designed for quite this exact use case: http://www.blosc.org/ and has nice python bindings. Cheers, Daniele
