Bass Boost1/SPhat1 enhancement blocks
Replaces the 74-parameter ADAU1701 program with the new 224-parameter
SigmaStudio export. The new netlist has no mixer -- MX1 is an
exclusive selector (DC1) passing through exactly one of three stereo
pairs (radio/bluetooth/beep) instead of blending them with independent
gains. core::MixSource/MixerState are gone; core::ActiveSource plus
IDsp::selectSource() replace applyMixer()/setInputVolume() throughout
the driver/service/API stack. AudioProfile.mixer -> activeSource;
the HTTP "mixer" JSON object -> a single "active_source" string.
DC1 turned out to need a raw 32-bit integer (0/1/2), not the 5.23
fixpoint its compiled TYPE_DC1 macro implies -- confirmed live by
writing both encodings and listening for which one actually switched
sources. Documented in Adau1701Driver::selectSource() and
adau1701::paramSourceIndex().
Bass Boost1 and SPhat1 are real ADI algorithm blocks in this revision,
so core::applyEnhancementsToEq() (the old EQ-band-overwrite hack for
bass/stereo enhancement) is deleted; IDsp::setBassBoostLevel()/
setStereoSpreadLevel() scale each block's compiled coefficients toward
identity/unity instead. Confirmed live: Bass Boost audible on real
program content (not a static test tone -- the algorithm is dynamics-
based), Stereo Spread audible but subtle. The EQ "locked" flag from
2026-08-24 (enhancements silently overwriting manually-set bands) no
longer applies to bands 1-5.
A full sweep of all 223 non-DC1 named parameters (writing each back to
its own compiled default) completed with zero failures, confirming the
whole new address space is reachable.

Streaming (main feature this session):
- New WebRadioConfig/WebRadioJson core types, ISecureStore-backed persistence
- New webradio::WebRadioService (thread-safe live config) + GET/POST /api/streaming
- web_radio_stream task now runtime-toggleable (no reboot), no hardcoded URL
- Content-Type diagnostic: warns clearly when a URL is a webpage, not an audio stream
Boot cleanup:
- Removed boot-time auto FM/DAB tune, auto-beep, and the (now-concluded) Si4684
crystal IBIAS/CTUN empirical sweep from main.cpp — tuning/beep are on-demand
via the existing REST API only
Web UI:
- Modernized styling (cards, gradients, toggle switches, light/dark theme)
- New Stream tab wired to /api/streaming
Fixes found via real idf.py build (not just clangd):
- Restored wrongly-removed si4684/Si4684Tuner.hpp include in main.cpp
- Fixed MP3Decode() argument types in web_radio_stream.cpp (unsigned char**/int*)
Quality-gate fixes:
- Host-test stub headers (esp_log.h, freertos/*) so TunerService.cpp's
scanForStation logging/pacing compiles for station_service_test /
integration_service_test instead of running stale binaries
- Added WifiScanner and WebRadioService manual sections; filled in missing
Doxygen docs on BluetoothService, i2s_sdata_probe, test_firmware, Bt1035At
- Ignore clangd's .cache/ index directory
Also includes prior uncommitted work carried in the tree: Wi-Fi/Bluetooth
device scan REST API and UI (WifiScanner, BT scan), SigmaStudio TCP bridge,
and the current ADAU1701 SigmaStudio DSP program export.
