Implements GET /api/audio/levels, reading all six 1×RTA level-detector
cells on demand (no background polling, no caching -- only runs when
called, per explicit request this session).
The read mechanism is the ADAU1701's documented Data Capture Register
(address 2074/0x081A, datasheet Rev.0 pp.30,36: write a (program-step,
register-select) pair to configure what the register mirrors, then
read back a 3-byte 5.19 twos-complement value). The per-meter program-
step indices are taken verbatim from SigmaStudio's own compiler output
(Firmware/ADAU1701-Firmware/IC 1_DigiRadioFinale/net_list_out2/
trap.dat), not invented -- the datasheet explicitly says these indices
must come from that compiler-generated file.
Confirmed live: all six points return distinct, plausible dBFS values,
and the output meters track a master-volume change.
Also folds two pieces of live user feedback into the app brief: the
volume slider should reach +12 dB (the firmware's real ceiling), not
stop at 0 dB, and the new levels endpoint is what a "VU meter" UI
section should poll instead of faking one.

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.

New core::IDsp::writeRawParam(address, value) safeloads any named
Parameter RAM cell in the compiled SigmaStudio program (74 cells: mixer/
Beep1/PEQ coefficients/limiter thresholds/etc — the same set SigmaStudio's
own Remote Connection, components/net/SigmaStudioTcpServer, already has
full access to). Value is a plain SigmaStudio floating coefficient,
converted to ADAU 8.23 fixpoint via the existing core::floatToFixpoint823.
Adau1701ParamTable.hpp holds the name->address table extracted from
Firmware/ADAU1701-Firmware/DigiRadio_IC_1_PARAM.h; core::DspParamJson
handles the wire format without core/ depending on the adau1701 driver
(net/SetupWebServer.cpp bridges the two, consistent with how other
JSON DTOs are supplied their data by the net layer).
GET /api/dsp/params lists every cell (name + address) for discovery.
PUT /api/dsp/param {"name":...,"value":...} writes one. Deliberately no
domain validation, matching the trust level already implied by the
existing SigmaStudio TCP bridge being reachable on the same network.
HTTP routes were registered in the SetupWebServer.cpp change committed
alongside the FM band scan feature (3a10ed7).

Claude-Session: https://claude.ai/code/session_0178rASQ6ZETPMUamvpoR2KR
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.

Decouple the SigmaStudio RAM download from compiled-in adau1701_program.c:
DRAD v1 blobs in the dsp partition with embedded fallback, POST /api/dsp/program,
and host-tested blob parse/serialize helpers.
