Struct EncoderConfig 

pub struct EncoderConfig {
    pub channels: u32,
    pub bits_per_sample: u32,
    pub sample_rate: u32,
    pub block_size: u32,
    pub compression_level: u32,
    pub md5: bool,
}

Audio format and compression settings for an Encoder.

Build one with EncoderConfig::new (libFLAC’s defaults: compression level 8, 4096-sample blocks, MD5 on) or EncoderConfig::chd (MAME/CHD’s exact configuration), then adjust with the with_* methods if needed.

Fields

channels: u32

Number of channels, 1–8. Stereo (2) enables mid/side decorrelation.

bits_per_sample: u32

Bits per sample: 8, 12, 16, 20, 24, or 32.

sample_rate: u32

Sample rate in Hz.

block_size: u32

Fixed block size in samples (the final frame may be shorter). libFLAC’s default is 4096; CHD uses 2048.

compression_level: u32

Compression preset, 0 (fastest) … 8 (smallest); values above 8 clamp to 8.

md5: bool

Whether STREAMINFO carries the audio MD5 signature (libFLAC’s --no-md5-sum, and CHD, set this false).

Implementations

impl EncoderConfig

pub fn new(channels: u32, bits_per_sample: u32, sample_rate: u32) -> Self

A config for the given format at libFLAC’s defaults: compression level 8, 4096-sample blocks, MD5 enabled.

pub fn chd(block_size: u32) -> Self

The exact configuration MAME/CHD uses: 2-channel / 16-bit / 44.1 kHz, compression level 8, MD5 off, and the given fixed block_size (CHD typically uses 2048). Pair with Encoder::encode_frames for the raw frame bytes CHD embeds.

pub fn with_compression_level(self, level: u32) -> Self

Set the compression level (0–8).

pub fn with_block_size(self, block_size: u32) -> Self

Set the fixed block size in samples.

pub fn with_md5(self, md5: bool) -> Self

Set whether STREAMINFO carries the audio MD5.
