No, it's not spyware IE Toolbar, as Clint would like us to think of this and almoust any other freeware listed in this site.
By the way, it's a great player able to play mpr, ogg, wav and cda with the help of winamp plugins.

Great little player with a very small footprint. Perfect, for me, to play MP3s off a portable HD.

As a musician this player has been 10x more valuable than any other Since it's keyboard controls are basic. Space pauses and plays while Return restarts the song 'from the top'. Why can't other players use simple keys for controls? (WinMediaPlayer = Ctrl-P, Ctrl-S?).

F8-F12 are nice controls while it's running in the background. Also the size is again a nice factor. Definately a must-have on your thumb drive.

Winamp (best version is 2.95 if you ask me) also simple key comands ^^ try it!

sadly the player freezes and crash all the time.
thats why port VLC is much better (you realy dont need an extra app for music only)

I love 1by1. It's fantastic. I actually had occasional crashing issues too until I changed the default MPEG audio decoder to ACM. Now, no crashes at all. The only thing that I wish it had was support for reading ReplayGain tags.

a 2006-10-28 18:59

1by1 is an awesome player, it doesn't do tags, or stupid playlist, it intuitivly lists the songs filenames instead. (although it does support tags and playlists) which is great because it's easier play/find the songs 'cause most songs have wrong id tags or none at all, and it *lists* the songs. i wish mp3 players were as robust as this.

note: it supports winamp plugins it can play stuff that winamp can play.

I went to the website and could not find a download link. Perhaps the author is working on the site. I guess I try back later.

Andrew Lee 2006-12-29 03:53

Click on the "Download" link above. Then look for a link called "download
http temporary (do NOT link!)" on the left-middle.

G. Robbins 2007-04-25 06:51

I've had 1 by 1 on my right click menu for a long time. This is a great player when you just want it to work and work quickly. Don't have to fiddle with anything and it doesn't try to sell you anything.

D 2007-08-01 21:59

Great product. Simple, no hassles, no useless graphic interface.

D 2007-08-01 22:01

1by1 available on the right click of the mouse is a great idea. Kudo to you, G.Robbins

DG 2007-08-08 09:17

Kuba, could you give a bit more detail on how to do WAV CDA and the like with the winamp plugins?

grannyGeek 2007-09-04 22:42

I'm still using and preferring this to other minimalist audio players (and "regular" players, for that matter). I set it to play a file folder with 8 hours of music files, and let it run all day.
Go to WinAmp site to get old plugins in_WAV.dll and in_CDreader.dll to play wav files and CDs.
(I already had ACM/AC3, Ogg, and Lame mp3 codecs installed that it could use.) Just drop those WinAmp plugins in the app's folder, and you can listen to just about everything.
Small is beautifuller :)

I 2007-11-10 14:41

Where can I get the plugins?
Please give more detailed information than "winamp.com". I didn't find there the basic plugins (WAV, WMA, CD).

grannyGeek 2007-11-14 00:23

I ---
here is link to a handful of plugins.
It took me hours & hours of searching, they were scattered all over the internet. But I NEEDED them for my work pc which didn't have 3rd-party codex that 1by1 could use.
Hope you see this comment, and that this helps.

theboydanny 2008-03-18 15:42

Thanks for the plugins grannyGeek.

itwriter 2008-04-07 12:37

Thanks from me, too, grannyGeek. And I can see why you didn't add an .m4a dll -- none of the ones I found work with 1x1 :-(

Patman 2008-04-10 21:12

This is a sweet player. I've tried nearly every audio player on this site, this one is far superior to any of the others. You can do playlists by the way. You just add a playlist folder to the 1 by 1 directory. Ive had no luck with imported playlists though, they have to be altered and then saved as m3u. Making m3u from Win Media player won't work either, you'll have to alter it.

Rafael 2008-05-08 06:34

The coolest of all mp3 players. All I think a mp3 player needs is to play mp3, stay in the tray, and have configurable hotkeys. And also be stable. HavenĀ“t tested stability, but the rest it has! Thanks alot!!! Goodbye lousy windows media player, I wont miss you freezing my pc.

a 2009-05-12 08:22

1by1 has problems with very large directories.. I have over 750 folders which causes it to become completely unresponsive and slow. I would love to stick this player but this is becoming a problem.

Bruce 2010-04-08 05:49

I have been using this through several versions for about two years or more. A great, straight-forward player, perfect for when you just want to play music in directories/folders, without having to setup playlists or libraries or whatever. Its windows explorer style tree view lets you see exactly what folders on your HD(s) you are listening to.

On my XP-SP3 machine, one of the high level music directories I have has 210 first level folders, 725 total folders, 2200 files, 7 GB total (at least, according to Win Explorer properties). It works fine in that setting -- I mention this just as FYI for poster "a" who said it was slow for their 750 folders.

And thanks to GrannyGeek for the collection of plugins. The one that I had located for myself was the in_wave.dll to let it play windows wav files. the other codecs will be useful. Thx.

Bruce 2010-04-13 09:12

Hi, just wanted to add that I have found 1by1 can now also play my aac/m4a tunes (which I ripped on my Mac) after I installed the in_mp4.dll. Woo-hoo! Now it is close to my perfect folder-based music previewer/player.

After bunch of fruitless searching, finally found that codec at free-codecs site, http://www.free-codecs.com/download/mp4_input_plugin_for_winamp.htm . Just run the installer and then copy the in_mp4.dll from the winamp\plugins to the \1by1 programfiles dir.

Vavo 2010-06-25 19:53

Works with EvilLyrics (seems also portable.. not fully tested just copied from other machine)

MarkB 2010-11-12 17:46

The new version (1.71) seems to be slower than the previous one.

MarkB 2011-04-03 17:15

Same problem with v. 1.73. V. 1.70 starts instantaneously, the more recent versions don't.


AbXy 2011-04-08 15:00

In case of a slow start: Settings - System - Hide A:

"1by1 - Plugin Pack" for other audio file formats (e.g. flac, ape, cda etc.):



ChipsNHotSauce 2011-06-14 01:22

Thanks AbXy!


freakazoid 2011-06-15 02:25

The addition of BASS support is a killer new feature!


MarkB 2011-06-15 14:14

Certainly, freakazoid, and with it streams support. But what the heck has the author done with the ID3v2 tags? 1by1 only displays raw strings now.


Nh 2012-04-13 07:25

This version (1.76) can't delete a file.


TP109 2012-10-09 06:42

I'm using ver 1.76 in XP and I can delete files to the recycle bin with the 1by1 context menu. To delete a file from the playlist only, use the keyboard "DEL" key.

The m4a plugin available at http://www.free-codecs.com/mp4_input_plugin_for_winamp_download.htm works great in ver 1.76.


Cattleya 2013-07-14 04:38

More information: If you want 1by1 100% portable without registry touch, please download mpglib.dll in official website and bass.dll (optional, improve audio experience only), and go to Options -> Decoder -> change decoder to mpglib.dll, go to System and tick Force portable....
And now we have a music play fully portable :)

Normally if we use ACM Decoder, Windows will touch and change this registry:

Windows Registry Editor Version 5.00

For a couple more *diminutive* audio players (one of which is just 4.6k !), check the forums here:



hamasaki 2013-10-27 20:56

My favourite player. Not over loaded with pointless skins and visuals. Just a nice easy to use player.


smaragdus 2014-08-17 19:42

1by1 version 1.82 is out.


Checker 2014-08-18 16:13

@ smaragdus: Thanks ... and updated ;)


Nh 2015-06-28 04:57

The last version - 1.84 - does not allow to change font in Settings... \ List style.


__philippe 2015-06-30 11:18

The official 1by1 (1.84) download link appears to be down currently...:-(

Try this one instead:


spicydog 2016-02-11 06:47

No other player needed on my system ;)
