The overlap audit against origin/main and the open pull requests found 39 of the 193 declared exports that must not be declared here: - 14 that origin/main already exports. The nid_patcher computes the NID of a symbol from its name, and a name ending in _nid_postfix exports the NID of the base name, so scePadOpen, sceNetInit and the rest are already there. - 23 that an open pull request provides: #6832, #6847, #6852, #7846, #7881, #7889, #7890, #6977 and #7690. - 2 whose technical-debt file an open pull request creates: #7463 and #8094. The scope is now 30 libraries and 154 exports.

libSceAudiodec technical debt
Unknown function info
- sceAudiodecDecode (libSceAudiodec) - a raw M4AAC stream carries no channel configuration, so the decoder tries the mono/stereo configuration and then configurations 3 to 7 within
ui_max_channelsuntil one decodes the first access unit, and keeps that one. No reference documents how the library picks the layout (shadPS4 maps the channel count straight to the configuration; SharpProspero only describes the maximum). With the stereo configuration a mono raw stream decodes as 2 channels, so 2 is reported, not 1 - sceAudiodecDecode (libSceAudiodec) - the HE-AAC handling follows one console measurement of an HE-AAC v2 ADTS stream: SBR output at 48 kHz in one channel with
ui_enable_heaac1, the 24 kHz mono core with 0. Not measured: whether the console, like FFmpeg, decodes a stream without SBR data in its first access unit as AAC-LC withui_enable_heaac1, and what it reports inui_sampling_freqandui_heaacwithui_enable_heaac0 (here the rate of the returned PCM and 0)
Functional
- sceAudiodecDecode (libSceAudiodec) - an ADTS stream with channel configuration 0 (layout in a program config element) is still parsed by FFmpeg, so
ui_enable_heaac0 does not remove its SBR and a mono one with Parametric Stereo comes out as stereo. - libSceAudiodec throws for the 24-bit PCM word size (
iBwPcm0): its sample layout is unknown. ATRAC9 decoding is covered only by configuration and error tests, as no ATRAC9 encoder is available for a fixture.
