Implementations

impl AudioProcessor

pub fn new(file_path: &str) -> Result<Self, AudioError>

Creates a new audio processor instance from a file path.

pub fn seek(&self, position: Duration) -> Result<Self, AudioError>

Seeks to a given time position and outputs a new file.

pub fn trim(&self, start: Duration, end: Duration) -> Result<Self, AudioError>

Trims the audio between start and end durations. Returns a new AudioProcessor instance with the trimmed segment.

pub fn transcode( &self, output_format: AudioFormat, output_path: &str, ) -> Result<(), AudioError>

Transcodes the current audio to a different format.

pub fn adjust_volume(&self, factor: f32) -> Result<Self, AudioError>

Adjusts the audio volume by a scaling factor.

pub fn change_speed(&self, factor: f32) -> Result<Self, AudioError>

Changes the playback speed (and optionally pitch) by a factor.

pub fn apply_effect(&self, effect: AudioEffect) -> Result<Self, AudioError>

Applies an audio effect using FFmpeg filters.

pub fn merge_audios( audios: &[AudioProcessor], output_path: &str, ) -> Result<Self, AudioError>

Merges multiple audio files sequentially (concatenation). Uses FFmpeg’s concat demuxer.

pub fn reverse(&self) -> Result<Self, AudioError>

Reverses the audio.

pub fn normalize(&self) -> Result<Self, AudioError>

Normalizes the audio volume.

pub fn overlay( &self, overlay_audio: &AudioProcessor, start_time: Duration, ) -> Result<Self, AudioError>

Overlays another audio onto this one at a given start time.
