Rtl_fm is a general purpose analog demodulator. It can handle FM, AM and SSB. It can scan more than a hundred frequencies a second. For digital modes, piping the audio into multimon-ng works very well. On a Raspberry Pi, rtl_fm + multimon uses just over half of the CPU. If you are interested in ADS-B decoding, check out the rtl_adsb utility. It uses only 6% CPU on a Raspberry Pi and can run on targets as small and adorable as a 16MB TL-R703N. If you are using Arch Linux, I've already packaged these tools for you and you can install them with pacman -S rtl-sdr. If you need something more specific, feel free to send me an email.
