The server benchmark's DAB+ input (vibe_benchmark_dab.h), fetched on first run so the APK and packages stay small.
A real DAB multiplex — eleven DAB+ services (one at 128 kbit/s, ten at 48) and one MP2 service — built entirely from generated audio, made-up station names and generated slides with ODR-DabMux/DabMod/AudioEnc/PadEnc. Nothing broadcast and nothing anyone else owns is in it. It is then damaged the way a weak signal on a cheap dongle is (a 20 us echo, three short fades, a 1.8 kHz offset, noise to 7 dB, 8-bit I/Q at ~30 counts RMS), because a clean signal never exercises the error correction that costs a slow box its CPU.
