The icon for audio used in the library and the toolbox

Audio is an asset category in the library. Audio assets can be used within a place through ExplorerImageIndex 11.pngSound objects.

User-uploaded audio

This is how the user would insert sound codes before 2009.

Before 2009, it was possible to upload sounds unmoderated and without limit.

From 2009 to 2013, sounds were only able to be uploaded to the catalog by administrators; most of which were provided by Roblox, RobloSam, or clockwork. The latter two still have all their uploaded audio available on their profiles to this day.

In late 2013, players are allowed to upload and publish their MP3 and OGG files on Roblox by purchasing them with Robux, if the audio does not violate the Terms of Service and does not have any copyrighted material. This allowed for a broader plethora of audio to be used in places.

In early 2014, Roblox's sound engine was changed so that audio is now more reliable in playback. Playback is nearly guaranteed, even if the audio asset hasn't been preloaded.

On March 9, 2022, Roblox replaced price limitations with a monthly limit to how many audio files users can upload and allowed free uploading as well. Users who have been ID verified are allowed to upload 100 files per month. Some other users are allowed to upload more than 100 files per month. All other users are allowed to upload 10 files per month.

Roblox also announced privacy changes that on March 22, 2022, all new audio uploaded will be Private and all existing audio with a length of over 6 seconds will be set to Private. Audio assets uploaded by Roblox and Monstercat will remain Public. Private audio cannot be used/played if the user/group did not upload the audio. Roblox recommends developers review and replace their audio. Roblox also added Audio Discovery Plugin to Roblox Studio which assists in finding and replacing audio.[1]

On March 17, 2022, Roblox announced an update to the audio privacy changes. Roblox will have a team to keep most sound effects Public, even if it's longer than 6 seconds. Roblox also partnered with Pro Sound Effects to bring lots of sound effects available to use by anyone. These sound effects are uploaded by Roblox and always end with (SFX). Roblox will also be adding "asset permissions" for audio, which allows users to grant permissions for which experiences can use them, or for all experiences.[2]

On the same day, Roblox also announced that users can fill out a survey to help Roblox suit the limit to the frequency and quantity of uploads to the user's needs in the future. Roblox is also announcing privacy for other asset types.

On March 22, 2022, Roblox will also partner with other music companies, such as Nettwerk Music Group and Position Music.


Audio files must be either MP3 or OGG and have a length of at most 7 minutes.

History of limitations

Audio prices before March 9, 2022
Length Price
< 0:10 20 Robux
0:10 - 0:59 35 Robux
1:00 - 1:59 70 Robux
2:00 - 7:00 350 Robux

When it was originally implemented, the system only allowed 15 seconds of audio and cost a player 250 Robux per audio asset, allegedly set up to prevent misuse of the feature. However, a loophole was discovered shortly afterward, in which players could technically upload a full song by speeding it up to the point where the song's duration is lower than 15 seconds, and creators could tweak the pitch to be lowered at a specific value (usually predetermined by the uploader in the description), for the full song to play normally, although losing some quality.

On January 15, 2014, Roblox increased the sound limit to 120 seconds, 8 times the length of the previous limit, and the cost decreased by 60% to 100 Robux, allowing longer audio to be uploaded for a lower price. The update proved to be successful, as it reduced the hassle of uploading multiple short samples of long audio and also reduced the complications that came with the pricing.

On March 18, 2015, Roblox allowed uploading of OGG files, which have more seamlessness looping than MP3 files.

On September 26, 2016, the sound limit was increased to 6 minutes, while the cost would be changed to a dynamic pricing system.

On October 6, 2016, the dynamic pricing system and limit of 6 minutes would be temporarily retired while some issues would be fixed. About a week later, the dynamic pricing system and limit of 6 minutes were returned.

As of December 1, 2016, the audio limit has been increased to 7 minutes.

On an unknown date in late 2018, the cost for audio was changed to 35 Robux instead of 75 for audio lengths ranging from 59 seconds to 2 minutes. Later in 2019, the cost for that length is now 70 Robux.

Before March 9, 2022, the prices for audio depended on the length. Audio that had a length of under 10 seconds would cost 20 Robux, 10 to 59 seconds would cost 35 Robux, 1 to 2 minutes would cost 70 Robux, and the rest would cost 350 Robux.

National Music Publishers' Association lawsuit

On June 9, 2021, Roblox was sued by the National Music Publishers' Association for copyright infringement for allegedly allowing the unauthorized use of copyrighted songs.[3]

After the lawsuit though not moderated; audios by the National Music Publishers' Association will no longer play in-game and will bring up error 46 in the client and attempting to search artist names on the audio tab in the Library will be blocked but not censored.

This is also likely the reason why all Accessories that allowed you to play custom audio were taken offsale in early 2021.

Sound ID

Location of Audio ID (outlined in red)

All audio, like other objects, is given a unique ID that can be found in the URL of their audio page. Unlike other objects, they do not need to be subtracted and are given directly. Audio IDs are used when creating Sound objects.

Downloading Roblox audio

Roblox doesn't provide a built-in feature to download any audio from the Library. However, third-party tools (such as the BTRoblox browser extension) allow downloading of audio (even Roblox's Licensed Music, which Roblox doesn't allow downloading).

APM Music

A 70's song uploaded by Roblox.

In late May 2018, Roblox signed a license agreement with APM Music, a music company that produces and licenses soundtracks for usage in films, TV shows, video games, and commercials. Soon afterward, thousands of APM Music tracks were uploaded onto the Library by Roblox, allowing developers various free music of any style for their experience without the risk of copyright infringement (given if they only use up to 250 per experience). More information can be found in this tutorial.

When Roblox did these massive uploads, the description was organized in this order:

  • the description of the song under "quotes";
  • the duration of the song in seconds (normally, for commercial purposes, many songs have cut versions to 60" and 30");
  • genre: there are many genres on Roblox, such as Club/Electronica, Jazz, Pop, etc.;
  • library: shows the library of the song. The most known are from Bruton, KPM, and Sonoton;
  • album: shows the album name;
  • the album info that you can search on the APM website;
  • and the "Courtesy of APM Music" phrase;

However, for some reason, the composer's/s' name(s) are not mentioned in the description. To find the composer's/s' name(s), you have to search the tracks yourself on APM Music itself.

Here's a step-by-step tutorial on how to find the composer's/s' name(s):

  1. Go to
  2. Type the song name in "Start your search..."
  3. Do not press enter. Instead, click on the correct title under "Track Title" to search for the specific song name.
  4. Type the name of the album in the search box.
  5. Click on the bold text under "Album Title".
  6. Hover over the correct track, and press the down arrow. The composer's/s' name(s) will appear. Ignore the percentage(s) and the "PRS/SACEM etc."

Alternatively, just copy and paste this link and replace the text in bold with the song title and album name.[{"field":"track_title","value":"Song title","operation":"must"},{"field":"album_title","value":"Album name","operation":"must"}]

Note: spaces are fine because of URL encoding.

These music tracks have been licensed for use in other video games as well. One example is the track "Ghost" from APM Music, created in 2004 and was also used in Plankton's Robotic Revenge back in 2013. Another example is "Fatal Error" from APM Music, used in the Skylanders series as the theme of the villain character Wolfgang. Both songs can be found in the audio marketplace.

Copyright claims on YouTube

Many people complained that they've been getting copyright claims (Content ID claims) from the licensed music in their videos because this music is copyrighted (These are not copyright strikes, meaning their videos are not taken down, but cannot be monetized).

Roblox allows users to post videos containing this music in their videos. The music, however, can only be used in Roblox gameplay videos.

Note: On the website, Roblox says "copyright takedown", but copyright takedowns will most likely never happen. Copyright claims are more common, but not strikes.

Copyright claims containing this music can easily be disputed (only if it is a Roblox gameplay video) using the following process:

  1. Go to the claims on YouTube
  2. Make sure the song is a song from APM Music (licensed by Roblox). If it isn't, you cannot dispute the claim.
  3. If you're 100% sure this song is from APM Music, go to "Select Actions".
  4. Select "Dispute".
  5. Check the box that says "My dispute isn't based on any of the reasons above. I would still like to dispute this Content ID claim.", and click on Continue.
  6. Select "License".
  7. Check the box that says "I have permission to use the content from the copyright owner."
  8. Mention that the song can be used in videos because it is used in a Roblox gameplay. The word "Roblox" has to be mentioned somewhere in the information.
  9. Check all of the boxes.
  10. Enter your full name (not a channel name).
  11. Click on "Submit".

Copyrighted audio removal

One of clockwork's audios that was removed for copyrighted material.

On May 30, 2018, Roblox announced on the Developer Forum that they would begin automatically removing any copyrighted audio (that is not part of Roblox's licensed audio library) from the site on June 18.[4] Audio that is removed for copyright has its name and description replaced with "(Removed for copyright)" and does not impact the uploader's moderation history. Originally, audios that were removed for copyright would be replaced with one of the songs in the table below when played inside an experience. However, this is no longer the case, and removed audios will not play anything.

Roblox has stated that the main reason for this is to give the Corporation itself better first impressions to future companies that they want to work with. Similar to the Pokémon Brick Bronze takedown, if an artist or record label found out that their music was being used by a site or user without permission (especially for monetary gain) then it would most likely lead to a lawsuit if action was not taken by the host.


On July 4, 2018, after the audio removal system was fully introduced, a bug that refunded users double the amount they spent to upload their removed audios caused many users to be falsely terminated by Roblox.[5] This was later fixed, although the terminations the bug caused sparked conversation about Roblox moderation within the developer community, notably in this devforum post by Cindering.

Following the introduction of copyright removal, many users began to upload audio that was modified in a way that bypassed Roblox's content identification system, typically by changing the pitch or adding an audio clip at the beginning.

This decision has been criticized for being quite sudden, and concerns over playable audio using custom Boombox passes in games have also been raised. Some argued that there would be no concrete way to prevent users from uploading copyrighted material and that games that rely on copyrighted music would be heavily crippled by the mass removal of audio.

Adult content incident

On June 22, 2018, the Roblox profile uploaded adult content in the form of audio. This likely occurred because the audio clip was improperly tagged as safe by APM Music, the source of the audio. After the audio was found by the community, Roblox transferred its ownership to a random inactive account and later deleted the audio. Along with the audio in question, the Roblox profile uploaded a safe version.

On March 9, 2022, a similar incident occurred when multiple songs that contained swear words in the title were uploaded to the Roblox account without being filtered or censored. Shortly after the audios were found by the community, the song titles were changed to "[ Content Removed ]" and the descriptions were removed.


On July 25, 2020, in addition to APM Music, Roblox also partnered with Monstercat so that their music can also be used freely in Roblox.[6]

Bypassed audio

Bypassed audios, or user-uploaded audio that contains inappropriate content, have commonly been found on the Roblox platform for as long as users could upload their own audios. Usually, bypassed audios are a product of faulty moderation, but there have also been bugs that allowed audio to be uploaded without being reviewed by moderation.

Before 2016, ExplorerImageIndex 11.pngSound objects could have a negative pitch, allowing audios to play in reverse. Because of this, many users uploaded inappropriate audios in reverse in hopes that it would be approved by moderation so that it could be played in reverse in-game.[7]

In 2014, a bug was discovered that allowed users to upload audio as a plugin to evade moderation. This bug caused many bypassed audios to be uploaded, although the bug was quickly fixed. However, a similar bug was discovered with RenderMeshes which caused more bypassed audios to be uploaded until the bug was eventually patched fully on April 26, 2017.

Users have continued to find more ways to bypass audio, including slowing and speeding up audios so that they create an inappropriate sound by changing the pitch of the audio in an experience, or leaving sections of silence in their audio in an attempt to trick moderation into approving the asset. In some cases, inappropriate audio has been uploaded directly and is still approved by Roblox moderation.

Beyond inappropriate sounds, there are many excessively loud or "ear-blaster" audios that get uploaded and approved even though they are against the Roblox Community Guidelines. These audios are commonly used in experiences where players can enter a custom audio ID to play (e.g. with a Boombox gear).

Audio privacy and upload changes

The Audio subcategory of the creator marketplace following the change

On March 22, 2022, all existing audios longer than 6 seconds (except those uploaded by Roblox) were made private as a part of Roblox's effort to allow creators to "control the availability, manner of distribution, and value of their creations." Private audios can only be used in experiences that are owned by the uploader or have been authorized to use the audio by the uploader.[8]

Along with this change, Roblox uploaded over 100,000 more licensed songs and sound effects to the audio library for use across the platform. The licensed audio was sourced from many partners, including Monstercat, APM, Pro Sound Effects, Nettwerk Music Group, and Position Music.[9]

Additionally, Roblox implemented a new system for audio uploads, giving all users a limited number of free audio uploads per month. Under the new system, non-ID verified creators could upload up to 10 audios per month, whereas ID-verified creators could upload 100. Additionally, some developers were given a limit of 2,000 uploads per month, but it is unknown what the criteria to receive this limit is, or if this is just random between players.

The changes to audio privacy were highly controversial within the developer community and the greater Roblox community, as evidenced by the replies to the original Developer Forum announcement, which received over 4,000 replies in 7 days. Many users were concerned about the impact these changes would have on their own game and things like the Boombox gears. Some also speculated that this change was forced due to Roblox's lawsuit with the National Music Publisher's Association, although this has not been confirmed by Roblox.
