Struct EchoHiding 

pub struct EchoHiding;

Echo hiding audio steganography adapter (STUB).

NOT YET IMPLEMENTED: Requires echo synthesis and autocorrelation.

TODO(T14): Implement echo hiding:

• Two echo delays (d0, d1) for bit 0/1
• Embed by adding delayed echo to audio
• Extract via autocorrelation peak detection
• Use array_windows for autocorrelation computation
• Requires audio DSP operations

Implementations

impl EchoHiding

pub const fn new() -> Self

Create a new echo hiding embedder.

Trait Implementations

impl Debug for EchoHiding

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

Formats the value using the given formatter.

impl Default for EchoHiding

fn default() -> EchoHiding

Returns the “default value” for a type.

impl EmbedTechnique for EchoHiding

fn technique(&self) -> StegoTechnique

The technique identifier for this implementation.

fn capacity(&self, _cover: &CoverMedia) -> Result<Capacity, StegoError>

Estimate how many payload bytes cover can hold.

fn embed( &self, _cover: CoverMedia, _payload: &Payload, ) -> Result<CoverMedia, StegoError>

Embed payload into cover, returning the stego cover.

impl ExtractTechnique for EchoHiding

fn technique(&self) -> StegoTechnique
