/// A ring buffer of audio data.
///
/// Each ring buffer has a producer (who writes to the buffer) and a consumer
/// (who reads from the buffer). Additionally, each ring buffer is associated
/// with a reference clock that keeps time for the buffer.
///
/// ## PCM Data
///
/// A ring buffer of PCM audio is a window into a potentially-infinite sequence
/// of frames. Each frame is assigned a "frame number" where the first frame in
/// the infinite sequence is numbered 0. Frame `X` can be found at ring buffer
/// offset `(X % RingBufferFrames) * BytesPerFrame`, where `RingBufferFrames` is
/// the size of the ring buffer in frames and `BytesPerFrame` is the size of a
/// single frame.
///
/// ## Concurrency Protocol
///
/// Each ring buffer has a single producer and a single consumer which are
/// synchronized by time. At each point in time T according to the ring buffer's
/// reference clock, we define two functions:
///
///   * `SafeWritePos(T)` is the lowest (oldest) frame number the producer is
///     allowed to write. The producer can write to this frame or to any
///     higher-numbered frame.
///
///   * `SafeReadPos(T)` is the highest (youngest) frame number the consumer is
///     allowed to read. The consumer can read this frame or any lower-numbered
///     frame.
///
/// To prevent conflicts, we define these to be offset by one:
///
/// ```
/// SafeWritePos(T) = SafeReadPos(T) + 1
/// ```
///
/// To avoid races, there must be a single producer, but there may be multiple
/// consumers. Additionally, since the producer and consumer(s) are synchronized
/// by *time*, we require explicit fences to ensure cache coherency: the
/// producer must insert an appropriate fence after each write (to flush CPU
/// caches and prevent compiler reordering of stores) and the consumer(s) must
/// insert an appropriate fence before each read (to invalidate CPU caches and
/// prevent compiler reordering of loads).
///
/// Since the buffer has finite size, the producer/consumer cannot write/read
/// infinitely in the future/past. We allocate `P` frames to the producer and
/// `C` frames to the consumer(s), where `P + C <= RingBufferFrames` and `P` and
/// `C` are both chosen by whoever creates the ring buffer.
///
/// ## Deciding on `P` and `C`
///
/// In practice, producers/consumers typically write/read batches of frames
/// on regular periods. For example, a producer might wake every `Dp`
/// milliseconds to write `Dp*FrameRate` frames, where `FrameRate` is the PCM
/// stream's frame rate. If a producer wakes at time T, it will spend up to the
/// next `Dp` period writing those frames. This means the lowest frame number it
/// can safely write to is `SafeWritePos(T+Dp)`, which is equivalent to
/// `SafeWritePos(T) + Dp*FrameRate`. The producer writes `Dp*FrameRate` frames
/// from the position onwards. This entire region, from `SafeWritePos(T)`
/// through `2*Dp*FrameRate` must be allocated to the producer at time T. Making
/// a similar argument for consumers, we arrive at the following constraints:
///
/// ```
/// P >= 2*Dp*FrameRate
/// C >= 2*Dc*FrameRate
/// RingBufferFrames >= P + C
/// ```
///
/// Hence, in practice, `P` and `C` can be derived from the batch sizes used by
/// the producer and consumer, where the maximum batch sizes are limited by the
/// ring buffer size.
///
/// ## Defining `SafeWritePos`
///
/// The definition of `SafeWritePos` (and, implicitly, `SafeReadPos`) must be
/// provided out-of-band.
///
/// ## Non-PCM Data
///
/// Non-PCM data is handled similarly to PCM data, except positions are
/// expressed as "byte offsets" instead of "frame numbers", where the infinite
/// sequence starts at byte offset 0.

/// Enables control and monitoring of audio gain. This interface is typically a

///
/// ## Knobs
///
/// This interface exposes two orthogonal knobs:
///
/// * The *gain* knob controls a single value in "relative decibels". A value of
///   0 applies no gain, positive values increase gain, and negative values
///   decrease gain. Depending on context, gain may be applied relative to an
///   input stream or relative to some absolute reference point, such as the
///   maximum loudness of a speaker.
///
///   This knob has no defined maximum or minimum value. Individual
///   implementations may clamp to an implementation-defined maximum value or
///   treat all values below an implementation-defined minimum value equivalent
///   to "muted", but this behavior is not required.
///
/// * The *mute* knob controls a single boolean value. When `true`, the
///   GainControl is muted and the effective gain is negative infinity. When
///   `false`, gain is controlled by the *gain* knob.
///
/// ## Scheduling
///
/// Changes to the *gain* and *mute* knobs can be scheduled for a time in the
/// future. Scheduling happens on timestamps relative to a reference clock which
/// must be established when this protocol is created.
///
/// TODO(https://fxbug.dev/42176154): scheduling semantics are subject to change
