If you’ve searched for the BPM or key of a song, there’s a good chance you’ve come across Tunebat.

Tunebat is an online collection of music tools designed for DJs, producers, musicians and artists. It is best known for its huge database of song keys and BPMs, but it now offers a much wider range of tools including audio analysis, vocal removal, mastering and music video creation.

You may also have come across a service called Vizfly.

Vizfly was an online music visualizer and music video creation platform. In 2020, Vizfly changed its name to Specterr, which continues to operate as an online music video and visualizer maker.

So, what exactly are Tunebat and Vizfly, and how can musicians use them?

What Is Tunebat?

Tunebat is a browser-based music database and collection of audio tools.

Its best-known feature allows users to search for almost any commercially released song and find information including:

  • BPM
  • Musical key
  • Camelot key
  • Popularity
  • Energy
  • Happiness
  • Release information
  • Record label information

Tunebat currently says its database contains harmonic data and recommendations for more than 70 million songs.

For DJs in particular, this information can be extremely useful when putting together mixes.

What Does BPM Mean on Tunebat?

BPM stands for beats per minute.

It measures the tempo or speed of a song.

For example, a song at 80 BPM will generally feel much slower than a song at 160 BPM.

DJs often look for tracks with similar BPMs because they can be easier to transition between during a DJ set.

Producers can also use BPM information when creating:

  • Remixes
  • Mashups
  • Samples
  • DJ edits
  • Cover versions

Tunebat makes it possible to quickly search for the BPM of a song without manually analysing the recording.

What Is the Tunebat Key Finder?

Another popular feature is the Tunebat Key & BPM Finder.

Instead of searching Tunebat’s existing database, you can upload your own audio file and have the platform analyse it.

Tunebat then attempts to identify the track’s:

Musical key and BPM.

This can be useful for producers working with audio files where the original key or tempo isn’t known.

For example, if you’ve received a vocal recording from another artist, knowing its musical key can make it much easier to build an instrumental around it.

What Is Camelot on Tunebat?

When searching Tunebat, you may notice codes such as:

8A, 8B, 9A or 9B.

These refer to the Camelot Wheel.

The Camelot system provides DJs with a simplified way of identifying musical keys that are likely to work well together.

Rather than having to remember relationships between keys such as A minor, C major and E minor, DJs can use the numbered Camelot system when planning harmonic mixes.

This makes Tunebat particularly useful for DJs trying to find songs that blend naturally together.

What Other Tools Does Tunebat Have?

Tunebat has expanded beyond simply being a BPM and key database.

Its current collection of audio utilities includes tools such as:

  • Key & BPM Finder
  • Vocal Remover
  • Song Mastering
  • BPM Tapper
  • Metronome
  • Music Video Maker
  • Key & BPM Changer

Tunebat also allows users to search its music database for tracks with particular musical characteristics.

That means Tunebat has increasingly become a broader toolkit for musicians rather than simply a database.

What Is Vizfly?

Vizfly was an online music video and audio visualizer creator.

Artists could upload their music and create visual content to accompany their tracks.

This type of tool is particularly useful for independent musicians who want to upload music to platforms such as YouTube without producing a traditional music video.

However, Vizfly no longer operates under the Vizfly name.

On July 15, 2020, Vizfly officially changed its name to Specterr.

What Happened to Vizfly?

Vizfly became Specterr.

According to the company, the original Vizfly name was too closely associated with audio visualisation.

The creators wanted to build a broader platform for helping artists create visual content and promote their music, so the company adopted the Specterr name instead.

If you’re therefore searching for:

Vizfly music visualizer

or

Vizfly music video maker

you’re effectively looking for what is now Specterr.

What Is Specterr?

Specterr is an online music video maker aimed particularly at musicians and creators.

Artists can use it to turn their audio into visual content such as:

  • Music visualizers
  • Lyric videos
  • Promotional music videos

Specterr describes its service as a way to create music visualizers and lyric videos online without needing traditional video editing software.

This can be useful for independent artists who have finished a song but don’t have the budget or resources to film a full music video.

Are Tunebat and Specterr Connected?

Tunebat and Specterr have historically been closely connected.

Oliver Reznik, who was involved in creating both services, described Tunebat and Specterr as two music-focused web applications being developed by his team.

Tunebat focused primarily on audio analysis, music discovery and production tools, while Specterr focused on music video creation.

That relationship also explains why Tunebat currently promotes music video creation alongside its other audio tools.

Is Tunebat Free?

Many of Tunebat’s basic features can be accessed directly through a web browser.

For most users simply trying to find the key and BPM of a song, the process is straightforward:

  1. Visit Tunebat.
  2. Search for a song or artist.
  3. Select the track.
  4. View its BPM, key and other musical information.

Alternatively, you can use Tunebat’s Key & BPM Finder to analyse your own audio.

Is Tunebat Accurate?

Tunebat can be extremely useful, but automatic audio analysis should still be treated as a tool rather than an absolute answer.

Software has to analyse the musical characteristics of a recording and estimate things such as its key and tempo.

For straightforward recordings, that can work very well.

More complicated songs containing key changes, unusual rhythms or ambiguous harmony can be harder for automated tools to analyse perfectly.

If you’re producing or mixing music professionally, it’s always worth checking the result with your ears and your own music software.

Who Should Use Tunebat?

Tunebat can be useful for:

DJs looking for compatible songs for harmonic mixing.

Music producers analysing samples, vocals and reference tracks.

Remixers trying to identify the BPM and key of an original recording.

Musicians trying to understand the structure of other songs.

Artists looking for tools to master, analyse or create visual content around their music.

Its simplicity is arguably one of the reasons Tunebat has become such a useful music utility.

Instead of opening professional production software simply to find a song’s BPM, you can search for it online in seconds.

Tunebat vs Specterr: What’s the Difference?

The easiest way to think about the two platforms is:

Tunebat = analysing and working with music.

Specterr/Vizfly = creating visual content for music.

Tunebat helps you understand and manipulate the audio itself.

Specterr helps you turn that audio into something visual that can be shared on platforms such as YouTube and social media.

For independent musicians, both types of tools can form part of the same release workflow.

You could analyse your track using Tunebat and then create a visualizer or lyric video for the finished release using Specterr.

What Is Tunebat? The Simple Answer

So, what is Tunebat?

Tunebat is an online music database and collection of tools that allows musicians and DJs to find information such as a song’s key and BPM, analyse their own music and access other audio utilities.

Vizfly, meanwhile, was an online music visualizer and video maker that was renamed Specterr in 2020.

Together, these types of browser-based tools make tasks that once required dedicated music or video software much easier for independent artists, DJs and producers.
