SDR service API

Assuming that ibm.sdr is the host name:

/freqs

Get a list of the frequencies of strong radio stations.

curl ibm.sdr:80/freqs

Example response: If the SDR hardware is present it will return a list of string FM stations. {"origin":"sdr_hardware","freqs":[89700000,91100000,91900000,93300000,94500000,95700000,96100000,97700000,99100000,101500000,102300000,103700000,105100000,107900000]}

If the SDR hardware is not present or can not be used for some reason it will return a single station of frequency 0. {"origin":"fake","freqs":[0]}

/audio/

Get a 30 second chunk of raw audio. curl ibm.sdr:80/audio/99100000

curl ibm.sdr:80/audio/99100000 | aplay -r 16000 -f S16_LE -t raw -c 1
