Fix the recursive base interface.

AudioContextOptions resolves to the interface declared here and causes TS2310. Extend the DOM interface instead:

-export interface AudioContextOptions extends AudioContextOptions {
+export interface AudioContextOptions extends globalThis.AudioContextOptions {

Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

MDN AudioContext suspend resume Promise reject InvalidStateError state suspended autoplay policy

💡 Result:

When using AudioContext, the suspend and resume methods return a Promise that resolves when the state transition is complete or rejects if the context has already been closed [1][2]. While these methods do not generally reject due to autoplay policy restrictions, the interaction between manual suspension and browser autoplay policies can lead to expected behaviors that may be confused with errors [3][4]. Key technical points regarding these operations: 1. Promise Rejection: The Promise returned by suspend or resume is primarily rejected if the AudioContext is in the closed state [1][2]. An InvalidStateError (or equivalent exception) is explicitly thrown if you attempt to call these methods on an OfflineAudioContext, as they are not supported for offline rendering [1][2]. 2. Autoplay Policy Interaction: Browsers often automatically suspend an AudioContext upon construction if the page lacks sufficient user activation [3][5]. In such cases, the context remains in a suspended state [6]. Calling resume in this state is standard practice and will trigger the resumption of the audio hardware once the browser's autoplay requirements are satisfied (e.g., following a subsequent user interaction) [3][5]. 3. No Automatic Rejection: If an AudioContext is suspended due to autoplay policy and resume is called before the user has interacted with the page, the promise does not necessarily reject; it may simply remain pending until the browser allows the audio to start [4]. Developers should design their applications to trigger resume specifically within the scope of a user-initiated event (such as a click or keypress) to ensure it executes successfully [5][7]. 4. Distinguishing States: There is no native flag to programmatically distinguish between a state suspended by the browser (autoplay policy) and a state suspended by the user (calling suspend) [3]. If your application calls suspend while the browser has already auto-suspended the context, you effectively layer a user-invoked suspension on top of the existing one, which must be accounted for if you intend to resume later [3].

Resume only contexts suspended by the visibility handler.

Track whether the handler successfully suspended the context, and resume only when that flag is set. Handle rejected suspend() and resume() promises. Invoke the handler once after registration so an initially hidden document is handled.

Web Audio API exponentialRampToValueAtTime zero endpoint specification behavior

💡 Result:

In the Web Audio API, the exponentialRampToValueAtTime method cannot reach a value of exactly 0 because the underlying mathematical formula for the exponential ramp, v(t) = V0 * (V1 / V0) ^ ((t - T0) / (T1 - T0)), would involve a division by zero or a result of zero, which is undefined for an exponential curve [1][2]. Historically, the specification dictated that an exception must be thrown if the target value (V1) or the value at the time of the previous event (V0) was less than or equal to 0 [3][4][1]. This remains the standard practice for developers, who typically use a very small positive value (e.g., 0.0001) instead of 0 to simulate reaching near-silence [5][6][7]. Recent developments and browser implementations have refined how these "illegal" cases are handled in practice. While earlier specifications and implementations strictly threw exceptions [6], modern browser behavior (such as in Firefox) has moved toward more graceful handling, such as maintaining the previous value (V0) when a zero or negative value is encountered, rather than crashing or throwing errors in all scenarios [8][9]. Despite this shift toward robustness, developers are strongly advised to avoid zero as a target or start value to ensure cross-browser compatibility and predictable audio output [5][6][7].

Web Audio API AnalyserNode getByteTimeDomainData array length shorter than fftSize specification behavior

💡 Result:

When using the Web Audio API's AnalyserNode, the getByteTimeDomainData method is designed to copy the current waveform (time-domain) data into a provided Uint8Array [1]. According to official MDN documentation, if the array passed to getByteTimeDomainData has fewer elements than the AnalyserNode.fftSize, the excess waveform data is dropped [1]. This behavior differs from the frequency-domain methods (e.g., getByteFrequencyData), which typically require an array with a length equal to the AnalyserNode.frequencyBinCount (which is defined as exactly half of the fftSize) [2][3]. Providing an array shorter than the required length for frequency data or the specified fftSize for time-domain data simply results in a partial copy of the available information, as the API does not throw an error but instead truncates the data to fit the provided buffer [4][5][1]. To ensure you receive the full set of time-domain data available for the current analysis frame, you should always initialize your buffer with a length equal to the current fftSize property of the AnalyserNode [1]. For frequency data, you should use frequencyBinCount [2][3].

Allocate time-domain buffers with analyser.fftSize.

frequencyBinCount is half of fftSize, so the current buffers return only half of the waveform samples. The Web Audio API truncates the excess samples. Use analyser.fftSize for both time-domain buffers.
