About

FluentDL is a Fluent UI desktop app for finding, matching, and downloading lossless audio (FLAC) at high speeds.

It automatically matches tracks across streaming services, gives you fine‑grained control over matches, and includes tools for format conversion, metadata editing, and quality inspection.

FluentDL supports Deezer, Qobuz, Spotify, and YouTube.

Why FluentDL?

If you have your own credentials and don't need a website downloader:

  • Performance: native desktop downloader for fast, multi‑threaded saving.
  • Control: review matches, edit metadata, and inspect audio quality with spectrograms.
  • All‑in‑one workflow: search, preview, match, download, convert, and tag in one app.
Search
  • Lookup songs/albums from any of the four online sources
  • Parse all tracks from an online link, with track/album/playlist links supported
  • Open songs/albums in preview sidebar to listen, download, or view metadata and available sample rates/bit depths
Local
  • View file metadata and technical audio specs in-depth
  • Edit file metadata, including option to change cover art
  • View file spectrogram to determine true lossless/quality
  • Convert between flac, mp3, aac, alac, vorbis, opus with specific bitrate or VBR
Queue
  • Matching between all possible combinations of online sources (e.g., convert Spotify and YouTube to Deezer equivalents)
  • Review matches and failures and find backups from other sources
  • Download tracks from Deezer, Qobuz, or Youtube with maximum quality
  • Inspect downloaded track spectrogram

See usage guide wiki to learn more.

Installation

Microsoft Store

You can download directly from the Microsoft Store for an easier and efficient update process.
Check out Releases to see full changelogs and sideloaded versions.

Store CLI (Windows 11 built-in)

Installation: store install fluentdl

Update: store update fluentdl

winget (Windows 10)

Installation: winget install --id 9MX44KM97X7X --source msstore --accept-package-agreements --accept-source-agreements

Update: winget upgrade --id 9MX44KM97X7X --source msstore --accept-package-agreements

Authentication

Note

Streaming services occasionally make changes to APIs, which may result in authentication issues. Check the Issues page for known problems and feel free to report them.

The authentication required depends on the sources and features you use.

Searching and Converting

For all sources except for Spotify, searches and conversions do not require authentication.

For Spotify, searches require API keys, which come bundled with FluentDL. If the bundled keys are rate limited, you can generate your own as described in the spotify wiki section.

Downloading

Authentication requirements for downloading varies for the sources. The type of account (free vs subscription) may also affect the audio quality available.

You do not have re-enter credentials each time because they are stored locally. They can be left alone for months or even longer, but may eventually expire or invalidate due to occasional web-player changes.

QobuzFree Account (30 second preview), Premium Account (up to 24bit/192khz FLAC)
SpotifyNot natively available. Use the Queue to convert song to other sources.

Retrieving Tokens

See the authentication wiki for a detailed guide.

About
FluentDL is a Fluent UI desktop app for finding, matching, and downloading lossless audio (FLAC) at high speeds.
It automatically matches tracks across streaming services, gives you fine‑grained control over matches, and includes tools for format conversion, metadata editing, and quality inspection.
FluentDL supports Deezer, Qobuz, Spotify, and YouTube.
Why FluentDL?
If you have your own credentials and don't need a website downloader:
  • Performance: native desktop downloader for fast, multi‑threaded saving.
  • Control: review matches, edit metadata, and inspect audio quality with spectrograms.
  • All‑in‑one workflow: search, preview, match, download, convert, and tag in one app.
Search
  • Lookup songs/albums from any of the four online sources
  • Parse all tracks from an online link, with track/album/playlist links supported
  • Open songs/albums in preview sidebar to listen, download, or view metadata and available sample rates/bit depths
Local
  • View file metadata and technical audio specs in-depth
  • Edit file metadata, including option to change cover art
  • View file spectrogram to determine true lossless/quality
  • Convert between flac, mp3, aac, alac, vorbis, opus with specific bitrate or VBR
Queue
  • Matching between all possible combinations of online sources (e.g., convert Spotify and YouTube to Deezer equivalents)
  • Review matches and failures and find backups from other sources
  • Download tracks from Deezer, Qobuz, or Youtube with maximum quality
  • Inspect downloaded track spectrogram
See usage guide wiki to learn more.
Installation
Microsoft Store

You can download directly from the Microsoft Store for an easier and efficient update process.


Check out Releases to see full changelogs and sideloaded versions.

Store CLI (Windows 11 built-in)
Installation: store install fluentdl
Update: store update fluentdl
winget (Windows 10)
Installation: winget install --id 9MX44KM97X7X --source msstore --accept-package-agreements --accept-source-agreements
Update: winget upgrade --id 9MX44KM97X7X --source msstore --accept-package-agreements
Authentication
Note
Streaming services occasionally make changes to APIs, which may result in authentication issues. Check the Issues page for known problems and feel free to report them.
The authentication required depends on the sources and features you use.
Searching and Converting
For all sources except for Spotify, searches and conversions do not require authentication.
For Spotify, searches require API keys, which come bundled with FluentDL. If the bundled keys are rate limited, you can generate your own as described in the spotify wiki section.
Downloading
Authentication requirements for downloading varies for the sources. The type of account (free vs subscription) may also affect the audio quality available.
You do not have re-enter credentials each time because they are stored locally. They can be left alone for months or even longer, but may eventually expire or invalidate due to occasional web-player changes.
