Struct ErbParams 

pub struct ErbParams { /* private fields */ }

ERB filterbank parameters

Implementations

impl ErbParams

pub fn new( n_filters: NonZeroUsize, f_min: f64, f_max: f64, ) -> SpectrogramResult<Self>

Create new ERB parameters with linear spacing (default).

Arguments

• n_filters - Number of ERB filters
• f_min - Minimum frequency in Hz
• f_max - Maximum frequency in Hz

Returns

SpectrogramResult<Self> - Ok with ErbParams if valid

Errors

Returns SpectrogramError::InvalidInput if:

• n_filters < 2
• f_min < 0 or not finite
• f_max <= f_min

pub const fn with_spacing(self, spacing: ErbSpacing) -> Self

Return a copy of these parameters with the given spacing strategy.

pub const fn with_db_floor(self, floor_db: f64) -> Self

Return a copy of these parameters that converts the output to dB.

Band energies below 10^(floor_db / 10) are clamped to floor_db.

pub const fn spacing(&self) -> ErbSpacing

Return the spacing strategy.

pub const fn n_filters(&self) -> NonZeroUsize

Get the number of ERB filters.

Returns

NonZeroUsize - Number of filters

pub const fn f_min(&self) -> f64

Get the minimum frequency.

Returns

f64 - Minimum frequency in Hz

pub const fn f_max(&self) -> f64

Get the maximum frequency.

Returns

f64 - Maximum frequency in Hz

pub const fn speech_standard() -> Self

Standard ERB parameters for speech (40 filters, 0-8000 Hz).

Returns

`Self - ErbParams with standard speech settings

pub fn music_standard(sample_rate: f64) -> SpectrogramResult<Self>

Standard ERB parameters for music (64 filters, 0-Nyquist).

Arguments

• sample_rate - Sample rate in Hz

Returns

SpectrogramResult<Self> - Ok with ErbParams if valid

Errors

Returns SpectrogramError::InvalidInput if:

• sample_rate <= 0

Trait Implementations

impl Clone for ErbParams

fn clone(&self) -> ErbParams

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ErbParams

impl Debug for ErbParams

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ErbParams

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ErbParams> for PyErbParams

fn from(inner: ErbParams) -> Self

Converts to this type from the input type.

impl PartialEq for ErbParams

fn eq(&self, other: &ErbParams) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ErbParams

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
