Аудио: встроенный проигрыватель

A music-player style audio block. Renders an uploaded or linked audio file with a custom control bar (play/pause, a waveform scrubber, volume, playback speed, loop), optional cover art, title/artist metadata, and a caption. Waveform peaks and duration are decoded once and cached in the saved data so playback renders instantly on reload. Audio is sent through a consumer-supplied uploader; when none is provided the tool falls back to a local blob URL (uploadByFile) or the pasted URL (uploadByUrl). Share links from Dropbox, OneDrive, GitHub, GitLab, Hugging Face, Google Cloud Storage, and the Internet Archive are rewritten to their direct-content form automatically; Google Drive links additionally require an `uploadByUrl` backend because Drive blocks browser hotlinking. An optional MIME allowlist and max size gate what is accepted.

Импорт

TypeScript

import { Audio } from '@bloklabs/core/tools';

Конфигурация

Опция	Тип	По умолчанию	Описание
`uploader`	`AudioUploader`	`undefined`	Consumer-supplied uploader with optional `uploadByFile(file, ctx)` (resolving to `{ url, fileName? }`) and `uploadByUrl(url, ctx)` (resolving to `{ url }`) methods. The `ctx.onProgress(percent)` callback reports upload progress. When omitted, audio falls back to a blob URL or the pasted URL.
`types`	`string[]`	`['audio/*']`	Accepted MIME allowlist. Entries may be exact (`audio/mpeg`) or family wildcards (`audio/*`). Defaults to any audio type.
`maxSize`	`MaxSizeConfig`	`30 MiB`	Max upload size. A number caps every type (bytes); an object caps per MIME type with `'*'` as the fallback.
`captionPlaceholder`	`string`	`"Write a caption…"`	Placeholder text shown in the caption field.
