this is the gap between heapTotal and the v8 heap space, this revels v8
internal memory.
fixes the npm build error.
Added support for playing tiktok videos.
After some researching and testing, aead_xchacha20_poly1305_rtpsize runs
natively on libsodum + has support for encrypt_into apis, that on my
machine, gave an 300% speed boost in decrypt/encrypt packets, since it
runs on sodium-native or libsodium-wrappers, only by running on these
packages makes it faster. Also tested with bun, sodium-native is still
faster than it by ~80%.
Fixed fadeTo/tapeTo/setFadeVolume silently no-oping on
connection.audioStream   (missing from _assignStream proxy)
Fixed 'audioStream' event listener being dead code (voice lib never
emits it)
Fixed 'reconnecting' connection status never firing (voice lib uses
connecting state, not reconnecting)
Fixed pause detection broken (voice lib uses idle+reason='paused', not
status='paused')
Fixed double-destroy race in _cleanupCurrentAudioStream
Fixed stuck detection conflict (set stuckTimeout above player threshold)
Fixed force=true reconnect being no-op when token+endpoint unchanged
Fixed ping -1 not caught by nullish coalescing

Implement setLoudnessNormalizer runtime toggle via
VolumeTransformer.setAGCEnabled
Handle circuit breaker disconnect reason
Update type declarations to match actual voice lib behavior
Remove 'seamless_bridge' from playing reason check, add 'unpaused'
Formmated the entire code with biome.
Replaced the circular ring buffer (RING_SIZE, writePos/readPos tracking,
swap buffer for wrap-around copies) with a straightforward leftover
strategy. Incoming chunks are concatenated with any leftover bytes using
bufferPool, full frames are encoded in a single pass, and remaining
bytes are saved for the next transform call. This reduces memory
overhead (no fixed 512KB ring allocation), eliminates wrap-around
complexity, and properly releases pooled buffers on error and flush.

After testing this for 2d, managed to get a 97% buffer reuse, which
alones gets an ~200/400mb saving in memory.
since its gonna be an LTS in october, and can run TS natively, i have
updated the experimental flag and fixed an error on config validator
causing it to crash on startup.
Since tidal does not seem to work now, will be default to qobuz.
Replaced the fragile NODE_UNIQUE_ID environment variable approach with
an explicit two-step identification protocol:

Master sends clusterId via IPC on fork
Worker confirms identity with HELLO packet (incl. PID) over event socket

Changed eventSockets from Set to Map keyed by worker ID. This enables
reliable mapping, stale socket cleanup on reconnect, and correct stats
attribution

Fixes an issue where /v4/workers showed complete stats only for worker
ID 1 all workers reported workerId: 1, so their stats overwrote each
other, leaving other worker IDs with only the initial { players: 0,
playingPlayers: 0 } stub.
resampler.destroy() was being called twice.
Lazily allocate tape/scratch effect buffers only when those effects are
used, instead of retaining them for every playback pipeline.

Lowered oversized AAC and WebM demux ring buffer defaults that were
retained per active stream.

Added teardown cleanup for playback filters and mixers so ended streams
release native buffers promptly.

From my tests on the playback worker, with 19 active players, the
JSArrayBufferData went from ~146MB to ~19.5MB.
This should help with client compatibility.

Symphonia v0.6.0
Rubato v2.0.0
And fixed FLAC playback, ig thats good.

New repo: https://github.com/ToddyTheNoobDud/symphonia-decoder
Pass abort signal into DASH segment fetches so stop() cancels in-flight
downloads. Refactor DASHHandler backpressure from data-event drain
detection to _read()-driven read-waiters. Replace .pipe() with
pipeline() for
proper error propagation and cleanup. Remove removeAllListeners() from
streamProcessor and AudioMixer in favor of owned listener cleanup.
Delete unreachable duplicate writableNeedDrain early-return in YouTube
recovery.

Also fixed an 403 error happening on bandcamp (by adding an Referer, and
fixed getTrackUrl capturing an trailing JSON.)
This seems to be no longer experimental and can be used in prod, since
bun got some major stability updates.
Also fix a crash ocurring during startup.

fix(youtube): resolve letterboxed hqdefault thumbnails
- Smooth equal-power volume curves to eliminate sudden audio changes

- Progressive vocal ducking ramp to keep speech clear without harsh cuts

- Multi-band crossover with clean bass swap to prevent low-end clashes

- Mid/Side 3D stereo morphing for smooth spatial transitions between tracks

- High-pass filter sweeps, vinyl tape stops, spinbacks, and dub delay tails

- Stutter build risers and energy lifting for seamless high-energy mix points

- Background pre-analysis queue to prepare queued songs ahead of time smoothly
- WebmOpus: count processed bytes that are actually skipped so large EBML
  elements no longer drop real Opus frames after the tag
- streamProcessor: skip the exact ADTS frame length instead of over-skipping
  into the next frame when a stream starts with garbage bytes
- HLS: end the stream when a live playlist finalizes with ENDLIST and the
  segment queue is already empty
- DASH: resolve relative SegmentTemplate and init URLs against the MPD URL
- CrossfadeController: use independent write positions for the left/right
  reverb comb filters so the stereo tail stays decorrelated
- NicoVideo: parse the full ISO-8601 duration instead of only the seconds part
- Gaana: derive the AES-CBC IV from the payload instead of a static IV
fix: resolve audio stream, demuxer, and source bugs
fix: prevent profiler file symlink escapes

routeplanner.ts has no dot in the filename, so it was getting registered
as a single static route at /v4/routeplanner instead of the actual paths
the handler dispatches on. every request to the route planner api was
404ing before the handler even ran, regardless of your routePlanner config
Since bilibili seems to be global now (as of the *.tv urls)
If a client keeps returning 403s, now it will fallback to the next
configured client instead of looping infinite retries.
this seems to be more realiable... again... Should fix android failing
to search some specific songs.
setup() now retries the player script and logs a warning instead of
failing source initialization. A late success self-heals since every
playback op calls getCachedPlayerScript() lazily anyway

(also removed the extra log i added for visitorData, i forgot since i
was testing it.)
should fix prefixes like "speak", "tts", "gtts", etc, not working.

this happens because while building the source name, GoogleTTSSource
produces googletts, while the actual name for it is google-tts. For
pipertts is just missing an extra 'tts' on it.
…ents

fix: prevent duplicate stream terminal events
fix: register routeplanner sub-routes correctly
- karaoke, tremolo, vibrato, rotation, distortion, echo, chorus, compressor, lowpass,
highpass, phaser, spatial rebuild a fresh object before applyAnimatedUpdate() and drop transition
fix: forward transition field in 12 AnimatableFilter subclasses
All thanks to: LuanRT/BgUtils#44 which is the
base for this commit.

Should fix sps 2 for most people hopefully.
This should fix when a error happens in sabr (eg: sps 2) the player kept
trying to recover the session even after it got destroyed.
skipMarginMs was accepted by the type and forwarded by the PATCH
handler, but never assigned in updateSponsorBlock, so it was
silently dropped.
fix: apply skipMarginMs in updateSponsorBlock
request shim was still using the old arrayBuffer-only path and
treating content-length: 0 as body (truthy string), also
Object.fromEntries collapsed set-cookie. now it checks len>0 ||
transfer-encoding and short-circuits for GET/HEAD, body handling is
a single arrayBuffer + emitEnd instead of the streaming reader mess.

ipc tracker was doing Buffer.byteLength(JSON.stringify(payload)) then
v8.serialize(payload) right after for process.send - double work
for every cluster message (kinda dumb). now its just
v8.serialize(payload).byteLength single pass.

added a small bun fast-path in makeRequest for stateless GET/HEAD
(no proxy/localAddress/streamOnly) - uses native fetch with abort
signal, falls back to http2/http1 on any error.
Now it should pages that return x-cache MISS,MISS, which og:url/html
doesn't contain the requested identifier.
Should fix clients not finding any player script to use hopefully.
