NamNode

Defined in: packages/chain/src/nodes/nam-node.ts:49

A NAM (Neural Amp Modeler) capture as a chain node.

The node applies no loudness gain of its own, deliberately. nam_process already implements NAM’s Normalized output mode internally — 10^((-18 - modelLoudness)/20), smoothed against clicks — which is the policy the workbench validated by listening. Applying it again here would double it. getInfo().loudness reports what the engine did so a host can show it.

The engine instance is created at prepare, not in the constructor, because instantiation is asynchronous and belongs to the caller. Until then the node passes audio through.

Constructors

Constructor

new NamNode(id?, name?, config): NamNode

Defined in: packages/chain/src/nodes/nam-node.ts:74

Parameters

id?

string = "nam-amp"

name?

string = "NAM Amp"

config

NamNodeConfig

Returns

NamNode

Properties

bypassed

bypassed: boolean = false

Defined in: packages/chain/src/nodes/nam-node.ts:55

Implementation of

ChainNode.bypassed

---

id

readonly id: string

Defined in: packages/chain/src/nodes/nam-node.ts:50

Implementation of

ChainNode.id

---

kind

readonly kind: "nam" = "nam"

Defined in: packages/chain/src/nodes/nam-node.ts:52

Implementation of

ChainNode.kind

---

latencySamples

readonly latencySamples: 0 = 0

Defined in: packages/chain/src/nodes/nam-node.ts:54

The engine adds no algorithmic delay; the buffer is in-place and sample-aligned.

---

mix

mix: number = 1.0

Defined in: packages/chain/src/nodes/nam-node.ts:56

Implementation of

ChainNode.mix

---

name

readonly name: string

Defined in: packages/chain/src/nodes/nam-node.ts:51

Implementation of

ChainNode.name

Methods

dispose()

dispose(): void

Defined in: packages/chain/src/nodes/nam-node.ts:195

Release resources the node holds outside the chain — a WASM instance, a file handle. Called on the node a chain drops: removeNode, clearNodes, and the replace-by-id path in addNode. Optional because most nodes hold nothing that outlives them.

Returns

void

Implementation of

ChainNode.dispose

---

getInfo()

getInfo(): NamNodeInfo

Defined in: packages/chain/src/nodes/nam-node.ts:139

Returns

NamNodeInfo

---

getParam()

getParam(id): number | undefined

Defined in: packages/chain/src/nodes/nam-node.ts:96

Parameters

id

string

Returns

number | undefined

Implementation of

ChainNode.getParam

---

getParams()

getParams(): Record<string, number>

Defined in: packages/chain/src/nodes/nam-node.ts:130

Returns

Record<string, number>

Implementation of

ChainNode.getParams

---

prepare()

prepare(sampleRate): void

Defined in: packages/chain/src/nodes/nam-node.ts:84

Parameters

sampleRate

number

Returns

void

Implementation of

ChainNode.prepare

---

process()

process(input): Float64Array

Defined in: packages/chain/src/nodes/nam-node.ts:161

Parameters

input

Float32Array<ArrayBufferLike> | Float64Array<ArrayBufferLike>

Returns

Float64Array

Implementation of

ChainNode.process

---

reset()

reset(): void

Defined in: packages/chain/src/nodes/nam-node.ts:90

Returns

void

Implementation of

ChainNode.reset

---

setModel()

setModel(modelJson): void

Defined in: packages/chain/src/nodes/nam-node.ts:153

Swap the model. The replacement is loaded into a new instance; the current one keeps running until the new one is ready, and is released only then. A refused model therefore never interrupts playback — the engine’s own reason is thrown and the old model stays.

Parameters

modelJson

string

Returns

void

---

setParam()

setParam(id, value): void

Defined in: packages/chain/src/nodes/nam-node.ts:111

Parameters

id

string

value

number

Returns

void

Implementation of

ChainNode.setParam
