Struct AudioTranscoder

pub struct AudioTranscoder { /* private fields */ }

Audio transcoder: Detects file format and converts non-WAV files to WAV.

Implementations

impl AudioTranscoder

pub fn new() -> Result<Self>

Create a new AudioTranscoder instance and initialize temporary directory.

pub fn needs_transcoding<P: AsRef<Path>>(&self, audio_path: P) -> Result<bool>

Check if the audio file at the specified path needs transcoding (based on file extension).

pub fn cleanup(self) -> Result<()>

Actively clean up temporary directory

impl AudioTranscoder

pub async fn transcode_to_wav_with_config<P: AsRef<Path>>( &self, input_path: P, min_success_rate: Option<f64>, ) -> Result<(PathBuf, TranscodeStats)>

Audio transcoding method with configuration, allowing specification of minimum success rate

pub async fn transcode_to_wav<P: AsRef<Path>>( &self, input_path: P, ) -> Result<PathBuf>

Transcode input audio file to WAV and save to temporary directory (backward compatibility).

pub async fn extract_segment<P: AsRef<Path>, Q: AsRef<Path>>( &self, input: P, output: Q, _start: Duration, _end: Duration, ) -> Result<()>

Extract audio segment for specified time range and convert to WAV.

Arguments

• input - Input audio file path
• output - Output WAV file path
• _start - Start time for extraction (currently unused)
• _end - End time for extraction (currently unused)

pub async fn transcode_to_format<P: AsRef<Path>, Q: AsRef<Path>>( &self, input: P, output: Q, _sample_rate: u32, _channels: u32, ) -> Result<()>

Transcode audio to specified format (WAV), ignoring parameters.

Arguments

• input - Input audio file path
• output - Output file path
• _sample_rate - Target sample rate (currently unused)
• _channels - Target channel count (currently unused)
