Struct SndFireface

pub struct SndFireface { /* private fields */ }

A GObject-derived object for sound unit of RME Fireface series.

The SndFireface is object class derived from GObject::Object for sound unit of RME Fireface series supported by ALSA fireface driver (snd-fireface).

For Fireface 400, the object class implements TimestampedQuadletNotification interface to dispatch event of knob control. The message parameter of event includes unsigned 32 bit integer value with encoded data. The kind of data can be detected by below flags:

• 0x00000100: MIDI message byte received in physical MIDI port 0
• 0x01000000: MIDI message byte received in physical MIDI port 1
• 0x04000000: signal level of channel

When it is for MIDI port 0, the value includes the message byte masked by 0x000000ff. When it is for MIDI port 1, the value includes the message byte masked by 0x00ff0000.

When it is for the signal level, the value includes paired channel position masked by 0xf0000000.

• 0x00000000: Microphone input 0/1
• 0x10000000: Line input 0/1
• 0x20000000: Line output 0/1
• 0x30000000: Line output 2/3
• 0x40000000: Line output 4/5
• 0x50000000: Headphone output 0/1
• 0x60000000: S/PDIF output 0/1
• 0x70000000: ADAT output 0/1
• 0x80000000: ADAT output 2/3
• 0x90000000: ADAT output 4/5
• 0xa0000000: ADAT output 6/7

When the value includes flag of 0x02000000, the value includes signal level for both of channels in the pair. Unless, when the value includes flag of 0x08000000, the signal level is just for right channel in the pair. When both flags are not found, the signal level is just for left channel in the pair.

The value includes signal level masked by 0x00fffc00. The range of signal level differs depending on channels. For signal level of microphone input:

• 0x00000000: zero
• 0x00002800: +10.0 dB
• 0x00002c00: +11.0 dB
• 0x00003000: +12.0 dB
• …
• 0x0000fc00: +63.0 dB:
• 0x00010000: +64.0 dB:
• 0x00010400: +65.0 dB:

For signal level of line input:

• 0x00000000: zero
• 0x00000400: +0.5 dB
• 0x00000800: +1.0 dB
• 0x00000c00: +1.5 dB
• …
• 0x00008800: +17.0 dB:
• 0x000008c0: +17.5 dB:
• 0x00000900: +18.0 dB:

For signal level of any type of output:

• 0x0000fc00: -infinite
• 0x0000f800: -58.0 dB
• 0x0000f400: -56.0 dB
• 0x0000f000: -54.0 dB
• 0x0000ec00: -53.0 dB
• 0x0000e800: -52.0 dB
• …
• 0x00001c00: -1.0 dB
• 0x00001800: 0.0 dB
• 0x00001400: 1.0 dB
• …
• 0x00000800: +4.0 dB
• 0x00000400: +5.0 dB
• 0x00000000: +6.0 dB

GLib type: GObject with reference counted clone semantics.

Implementations

impl SndFireface

pub const NONE: Option<&'static SndFireface> = None

pub fn new() -> SndFireface

Instantiate SndFireface object and return the instance.

Returns

an instance of SndFireface.

Trait Implementations

impl Clone for SndFireface

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SndFireface

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SndFireface

fn default() -> Self

Returns the “default value” for a type.

impl HasParamSpec for SndFireface

type ParamSpec = ParamSpecObject

type SetValue = SndFireface

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str) -> ParamSpecObjectBuilder<'_, SndFireface>

fn param_spec_builder() -> Self::BuilderFn
