Understanding XSPF files

What is a XSPF file?

XML playlist format referencing audio files

XSPF files are playlist files that reference actual audio files. XSPF files are similar to M3U files, but they use XML tags to organize and list files included in the playlist. The actual audio files are not stored within XSPF files, they are only referenced by them. XSPF files are used by various audio players, such as VLC media player, AIMP, Clementine, and Audacious.
If you are trying to transcribe XSPF files, you’ll normally need to upload the underlying audio files to Sonix so that we can transcribe all of the audio data properly. Please convert the underlying audio files to either MP3, WAV, or OGG file formats for us to better transcribe the spoken audio in those files.

Common uses for XSPF files

  • Audio playlists
  • Media player libraries
  • VLC Media Player
  • AIMP
  • Clementine

Who works with XSPF files?

Developers of open-source media players and web-based jukebox applications use XSPF to pass playlists between programs, since its XML structure stores portable track references rather than software-specific paths. Internet radio curators and music bloggers also publish XSPF files so listeners can load a shared track lineup into any compatible player.

XSPF vs MP3: which should you use?

An XSPF file is an XML playlist that stores references to audio tracks, while an MP3 file contains the compressed audio data itself. A media player reads an XSPF file to queue MP3s or other audio files in order, but the playlist holds no sound of its own. Use XSPF when you want to organize or share a track list, and work with the underlying MP3 files when you need to play back or transcribe the actual audio.

XSPF conversion FAQ

XSPF captions: frequently asked questions

Can you create closed captions from XSPF files?

Yes! Sonix transcribes your XSPF file with precise timestamps and creates closed captions in standard formats.

What's the difference between subtitles and closed captions?

Closed captions include non-speech elements like [music], [applause], and speaker identification. They're designed for deaf and hard-of-hearing viewers.

Are Sonix captions ADA compliant?

Yes! Sonix captions meet accessibility requirements when properly reviewed and edited. Our editor helps ensure timing and accuracy standards.

What caption formats are supported?

Export captions as SRT, VTT, or TTML. Each format has specific use cases.

Can I add sound descriptions?

Yes! Use our editor to add [music], [laughter], and other non-speech descriptions for full accessibility.

Do captions help with SEO?

Absolutely! Captions make your video content searchable and improve accessibility, both of which can boost SEO rankings.

Can I convert an XSPF file to text?

Not directly, because an XSPF file is a playlist that contains no audio data, only references to audio files. Locate the MP3, WAV, or OGG files it points to, upload those to Sonix to transcribe them, then edit and export the transcript.

How do I find the audio files referenced in an XSPF playlist?

Open the XSPF file in a text editor or a player like VLC; each track's location tag lists the file path or URL of the actual audio file. Those referenced files are what you upload for transcription.

What is the difference between XSPF and M3U playlists?

Both are playlist formats that reference external audio files rather than storing audio themselves. XSPF organizes its entries with structured XML tags, while M3U is a simpler plain-text list of file paths.
