Onset detection function

Variants

Energy

Energy based onset detection function

This function calculates the local energy of the input spectral frame.

Hfc

High Frequency Content onset detection function

This method computes the High Frequency Content (HFC) of the input spectral frame. The resulting function is efficient at detecting percussive onsets.

Trait Implementations

impl AsNativeStr for OnsetMode

fn as_native_str(&self) -> &'static str

Implementations should return strings ended with ‘\0’ (for ex.: "energy\0")

fn as_native_cstr(&self) -> *const c_char

Get constant as null-terminated C-string

fn as_rust_str(&self) -> &'static str

Get constant as rust string slice

impl AsRef<str> for OnsetMode

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for OnsetMode

fn clone(&self) -> OnsetMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OnsetMode

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

Formats the value using the given formatter.

impl Default for OnsetMode

fn default() -> Self

Returns the “default value” for a type.

impl Display for OnsetMode

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

Formats the value using the given formatter.

impl FromStr for OnsetMode

type Err = Error

The associated error which can be returned from parsing.

fn from_str(src: &str) -> Result<Self>

Parses a string s to return a value of this type.

impl Hash for OnsetMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for OnsetMode

fn eq(&self, other: &OnsetMode) -> 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 Copy for OnsetMode

impl Eq for OnsetMode

impl SpecMethod for OnsetMode

impl StructuralPartialEq for OnsetMode
