Music Player

The Music Player plays audio files that are already on your computer or phone. Pick several songs at once and they join a playlist on the page and play one after another, with previous, next, pause, and playback speeds from 0.5x to 2x. It is a simple local player. There is no music library, no lyrics, no cover art and no equalizer, and it does not remember your playlist: once the page is closed, the list is gone.

How to use it

1. Click the dashed area "Click to select audio files (multiple allowed)" and choose one or more audio files. Click again at any time to add more; new songs go to the end of the list.
2. After the first files are added, the first track starts playing automatically. The page shows the current track name (the file name without its extension) and the playback controls.
3. Use the round button in the middle to play or pause, and the buttons on either side for the previous or next track. Below them is the browser's own audio bar for seeking and volume.
4. The "Speed" row offers 0.5x, 0.75x, 1x, 1.25x, 1.5x and 2x. Click one to switch; the chosen speed stays when the track changes.
5. In the "Playlist" section, click a row to play that track, or click the X at its end to remove it from the list.

A practical scenario

Say you recorded several interviews on your phone and want to review them on a computer. Select all the recordings at once and they enter the list in the order you picked them. Click 1.5x to move quickly through slow stretches, and drop to 0.75x for the parts you need to transcribe word by word. You do not need to install anything or upload the files anywhere. If your browser does not recognise the format of one file, the page tells you to convert it first.

Supported range and known limits

• The file picker does not restrict formats, but whether a file plays depends entirely on which codecs your browser supports. MP3, WAV, OGG and AAC/M4A usually play reliably, while FLAC, APE and older WMA files may not. When a track cannot be played, the page shows a notice saying so. If needed, the Video Format Converter tool can extract audio into MP3 and other formats.
• The playlist loops: after the last track it returns to the first, and with only one track it repeats that track. There is no shuffle, no single-track repeat switch and no sorting.
• Track names come straight from file names. Embedded titles, artists, cover art and lyrics are not read.
• The playlist lives only in the page's memory. It is not saved, so you must add your files again after refreshing or closing the page.
• Known limitation: removing the track that is currently playing stops playback rather than moving on to the next song.
• Files are read and played by the browser directly. Very large files, such as long lossless recordings, use a lot of memory and may stutter on low-end phones.

FAQ: Why won't some songs play?

Browsers include only some audio decoders. The same file extension does not guarantee the same encoding: one .m4a file may use AAC and play fine while another uses a different codec and does not. If a track fails, the page says so. Converting it to MP3 or M4A and trying again usually solves it.

FAQ: Does changing speed change the pitch?

Speed changes are handled by the browser's audio engine. Modern browsers generally try to preserve pitch when the rate changes, but the result varies by browser and by the audio itself, and at extremes such as 2x or 0.5x some distortion is normal.

FAQ: Is my playlist still there after I close the page?

No. Nothing is written to storage. Each song is only a temporary reference to a local file you chose during this visit, so you need to add the files again next time. It also means your files never leave your device.

FAQ: Does it work on a phone?

Yes, you can pick local audio and play it in a mobile browser. Background playback rules differ between mobile browsers, though, so switching apps or locking the screen may pause the music. That depends on your system and browser, and the tool does nothing special to change it.

Privacy and how files are processed

Your audio files are only played inside your browser. For each file the page creates a temporary link that is valid on your device alone and gives it to the audio player. Nothing is uploaded to a server and no account is needed. Those temporary links are released when you leave the page. The tool does not record what you listen to and does not save your playlist.
