Examples

For now, you can only compute limitation threshold for some limiter types. More functions are planned to be implemented.

Limiter threshold calculator :

import {
    ChargeTypeEnum,
    computeLimiterThreshold,
    LimiterThresholdParams,
    LimiterTypeEnum
} from 'sono-toolkit'

const params: LimiterThresholdParams = {
    limiterType: LimiterTypeEnum.DBU,
    chargeType: ChargeTypeEnum.CLOSE,
    hpPower: 1600,
    impedance: 4,
    ampPower: 2000,
    ampGain: 32
}

const limiter = computeLimiterThreshold(params);
console.log(limiter)
// Outputs 4.5 in dB
Copy

Available limiter types are :

• dBu
• T.Racks DS2/4
• Behringer DCX 2496

Compressor attack calculator :

import {
    computeCompressorAttack
} from 'sono-toolkit'

const attack = computeCompressorAttack(90);
console.log(attack)
// Outputs 12 in ms
Copy

Compressor release calculator :

import {
    computeCompressorRelease
} from 'sono-toolkit'

const release = computeCompressorRelease(90);
console.log(release)
// Outputs 354 in ms
Copy

Tests

To run the test suite, first install the dependencies:

npm install
Copy

Then run npm test:

npm run test
Copy
