Flutter Soloud Volume Pan is an agent skill from alnitak/flutter_soloud. Teaches volume, pan, fade, oscillator, and scheduled-stop control in the fluttersoloud package, including the handle-based model, setPanAbsolute, getApproximateVolume for VU meters, and the limiter filter as the anti-clipping tool. Use when the user asks to change a sound's volume, pan a sound left/right, fade or oscillate audio parameters, build a VU meter, or stop clipping when many sounds play at once.
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile, covering Cross-platform mobile apps. It works with Flutter and Dart. The repository describes itself as: Flutter low-level audio plugin using SoLoud C++ library and FFI. The licence is MIT.
Read from SKILL.md and the folder at commit 289697e. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:

No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Flutter Soloud Volume Pan loads about 1.7k tokens when it runs. Until then it costs about 109 tokens; SKILL.md has 672 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/flutter-soloud-volume-pan/SKILL.md (or your agent's skills folder).Volume and pan in flutter_soloud are applied to handles (one per playing
voice), not to the loaded AudioSource. Loading a sound gives an AudioSource;
each play() returns a SoundHandle you control afterwards. Global volume is
engine-wide and multiplies with per-handle volume. Fades, oscillations, and
scheduled pause/stop run on the engine's internal fader clock, not on Dart
timers.
import 'package:flutter_soloud/flutter_soloud.dart';
Future<void> main() async {
await SoLoud.instance.init();
final source = await SoLoud.instance.loadAsset('assets/sfx.ogg');
// volume and pan can be set at play time...
final handle = SoLoud.instance.play(source, volume: 0.8, pan: -0.5);
// ...or changed afterwards on the handle.
SoLoud.instance.setVolume(handle, 0.6);
SoLoud.instance.setPan(handle, 0); // 0 = centered
// Fade out over 2 s, then stop 2 s from now.
SoLoud.instance.fadeVolume(handle, 0, const Duration(seconds: 2));
SoLoud.instance.scheduleStop(handle, const Duration(seconds: 2));
SoLoud.instance.setGlobalVolume(0.9); // master volume, all sounds
}All members of SoLoud.instance. Everything throws
SoLoudNotInitializedException if init() has not completed.
Per-handle volume / pan:
void setVolume(SoundHandle handle, double volume) / double getVolume(handle) —
0.0 muted, 1.0 full. Per-voice gain; multiplies with global volume.void setPan(SoundHandle handle, double pan) / double getPan(handle) —
-1.0 = full left, 0.0 = CENTER, 1.0 = full right. Diverges from
audioplayers (whose setBalance uses the same range) and from just_audio
(no pan at all), but trips up models assuming 0..1: setPan(handle, 0.5) is
half-right, not "half volume". Debug builds assert the range; release builds
clamp to -1..1.void setPanAbsolute(SoundHandle handle, double panLeft, double panRight) —
sets the L/R channel volumes directly (each -1..1). Bypasses the pan law.
Does not affect what getPan returns.Global:
void setGlobalVolume(double volume) / double getGlobalVolume() —
0.0..1.0, affects every voice.Fades (signature: (handle, to, Duration time), global variant omits the
handle):
void fadeVolume(SoundHandle handle, double to, Duration time)void fadePan(SoundHandle handle, double to, Duration time)void fadeRelativePlaySpeed(SoundHandle handle, double to, Duration time) —
ramps playback speed (and pitch, since SoLoud resamples).void fadeGlobalVolume(double to, Duration time)Oscillators (signature: (handle, from, to, Duration time) — time is the
full period of one from→to→from cycle):
void oscillateVolume(SoundHandle handle, double from, double to, Duration time)void oscillatePan(SoundHandle handle, double from, double to, Duration time)void oscillateRelativePlaySpeed(SoundHandle handle, double from, double to, Duration time)void oscillateGlobalVolume(double from, double to, Duration time)Scheduled actions (engine-clock, no Dart Future.delayed needed):
void schedulePause(SoundHandle handle, Duration time)void scheduleStop(SoundHandle handle, Duration time)Metering:
double getApproximateVolume(int channel) — per-output-channel post-mix
level for VU meters (channel 0 = left, 1 = right in stereo).
Only returns non-zero when visualization is enabled:
SoLoud.instance.setVisualizationEnabled(true) first.
Returns 0 for an invalid channel index.Simultaneous sounds sum and clip. Two voices at volume 1.0 can exceed full scale and distort; lowering volumes per-sound is a losing battle. The intended fix is the global limiter filter, which caps the mixed output:
await SoLoud.instance.init();
SoLoud.instance.filters.limiterFilter.activate();
// Optionally lower the ceiling (dB, should stay < 0):
SoLoud.instance.filters.limiterFilter.outputCeiling.value = -3;See the sibling skill flutter-soloud-filters for filter details.
Fades/oscillations keep running on stopped handles. If a handle is
stopped (or scheduleStop fires) mid-fade, the fader is not cancelled; when
the same sound is played again and the handle id is recycled, the old ramp
can snap the new voice's volume/pan. Reset the parameter explicitly
(setVolume/setPan) when starting a new voice if you previously faded.
getVolume/getPan/getGlobalVolume round-trip through float.
Reading back 0.8 can return 0.800000042353. Never compare with ==.
Handles die. After a sound ends or is stopped, the handle is invalid.
setVolume on a dead handle fails silently on the native side; check
getIsValidVoiceHandle(handle) if unsure. Don't cache handles across
stop()/scheduleStop().
getApproximateVolume returns 0 forever if visualization was never
enabled — it reads the same analysis buffers as the waveform/FFT feature.
setRelativePlaySpeed(handle, 0) is undefined behavior (likely crash);
the lower bound is silently clamped to 0.05. Same applies to
fadeRelativePlaySpeed / oscillateRelativePlaySpeed targets.
Max voice count is 16 by default. Extra play() calls steal the oldest
voice of the same sound (or are dropped with a log warning — no exception),
so a fade targeting the stolen handle does nothing. Raise with
setMaxActiveVoiceCount if needed.
Fades are synchronous calls, not Futures. fadeVolume returns
immediately; if you need to act when the fade finishes, await your own
Future.delayed with the same duration.
