See “file_player” in config. Requires updated csdr with —bigendian option to convert_s16_f and iq_swap_ff. Also requires xzcat to be installed. Sample files in new samples/ subdirectory. If larger sample file is too big for distro remove it and reconfigure to use smaller one (which will wrap around more quickly).
