Embed an audio file directly into HTML/XML using Base64 encoding

Description

Designed for inline use in R Markdown, e.g. `r provide_audio("media/klammer.wav")`.

Usage

provide_audio(
  path,
  mime = NULL,
  method = c("object", "audio"),
  warn_size_mb = 5
)

Arguments

path	Path to the local audio file.
mime	MIME type. If NULL, it is guessed from the extension.
method	Rendering method: "object" (default) "audio"
warn_size_mb	Warn if file is larger than this many MB.

Details

The function reads a local audio file, encodes it as Base64, and returns either:

• an HTML <object> tag

• or an HTML <audio> tag

This makes the final XML/HTML fully self-contained.

Value

knitr_asis object containing embedded audio HTML.
