Enum ndk::aaudio::AAudioInputPreset

#[repr(u32)]
pub enum AAudioInputPreset {
    Generic,
    Camcorder,
    VoiceRecognition,
    VoiceCommunication,
    Unprocessed,
    VoicePerformance,
}

Defines the audio source. An audio source defines both a default physical source of audio signal, and a recording configuration.

Note that these match the equivalent values in MediaRecorder.AudioSource in the Android Java API.

Added in API level 28.

Variants

Generic

Use this preset when other presets do not apply.

Camcorder

Use this preset when recording video.

VoiceRecognition

Use this preset when doing speech recognition.

VoiceCommunication

Use this preset when doing telephony or voice messaging.

Unprocessed

Use this preset to obtain an input with no effects. Note that this input will not have automatic gain control so the recorded volume may be very low.

VoicePerformance

Use this preset for capturing audio meant to be processed in real time and played back for live performance (e.g karaoke). The capture path will minimize latency and coupling with playback path. Available since API level 29.
