1. My favorite Music Key Finder Software for Windows: I liked KeyFinder the most as it is a dedicated software which can find song key as well as lets you write the fetched key information to the song. Rapid Evolution is another good software to find music key, BPM, replay gain, and beat intensity.
2. Song Key & BPM Finder Upload your audio files to find the key and tempo of the tracks in your library. This is a tool for DJs interested in harmonic mixing, producers looking to remix songs, and anyone trying to understand their music a little better. Browse or drag and drop audio files here to analyze your music.

The problem with this and any key detection software is accuracy, some are next to useless. DJ Techtools do yearly comparisons. The best come in at 86% accurate, the worst at around 40%. There are also songs that aren't in straight major or minor keys (mixolydian for example) or have key changes, or tuned sharp or flat.

Can be used in native apps on Android, iOS, macOS, tvOS, Linux and Windows, and in all major web browsers: Chrome, Firefox, Safari, Edge, Opera, etc.

The Superpowered Analyzer

Ever wondered how DJ and waveform editor software analyze audio? No need to worry, we packed everything into the analyzer. It's Superpowered of course: your users will be amazed how quickly your software analyzes audio.

• Bpm (beats per minute) detection to get the tempo.
• Key detection to get the main harmonic chord of the music.
• Easy helper tables to get the key in musical, Camelot or Open Key notations.
• Loudness/peak analysis to detect the average and peak volume.
• The average loudness of the 'loud' music parts is returned as well (excluding breakdowns and other quiet parts), to get 'real' average loudness data.
• Beatgrid information shows where the beats and bars start (beat and bar onset detection).
• Average and peak waveform data in compact form with 150 points/sec resolution.
• Compact music structure data, average decibels in 1 points/sec resolution

Waveform

The SuperpoweredAnalyzer provides you great waveform data, but sometimes you need the peak waveform only. This class offers you the quickest and highest performance way to do just that.

Bandpass Filterbank

A bank of bandwidth bandpass signal filters. Perfect for real-time analyzers (RTA) or offline usage, and has much higher performance than any FFT-based solution.

Very simple to use: just set up the frequencies and widths, and call process(). In addition to the frequency bands, the sum and peak of the incoming signal is returned too, so you get the average and peak volume.

Live Analyzer

Returns continously updated bpm and dominant key information of any real-time audio stream.

As big proponents of harmonic mixing, the DJ TechTools staff started out with a simple question: which program that analyzes a song’s key gives the most accurate results? To find out, we looked up the keys using sheet music for a selection of 50 pop/rock songs and then analyzed those songs using four key-detecting apps: BeaTunes 2, Mixed In Key 4, MixMeister Fusion and Rapid Evolution 2. Read on to find out the results.

THE KEY MAKERS

For our 50 test songs comprising recent hits and vintage classics (in MP3 and AAC formats), I took the keys from the digital sheet music site MusicNotes.com and compared those keys with each software program’s results. The Camelot System wheel was used to determine if an analyzed key was not correct but compatible with the actual key. The Camelot System assigns all keys an alpha-numeric value; and for example, keys compatible with 4A are 3A, 5A and 4B: plus or minus one number or the same number with a different letter. Scroll all the way down for tables with all the specific results.

Correct: 14 (28%)

Compatible: 18 (36%)

Incorrect: 18 (36%)

What else it does: BeaTunes 2 is an excellent complimentary program for iTunes. It helps you clean up your iTune Library by finding and correcting errors in the artist, album, title and other tags; searching for and adding other metadata such as album artwork, organizes songs with a color-coding system; determines BPM automatically or manually; and more. All of its changes are reflected in iTunes as well.

Price: $31.95 US for Mac or Windows

Correct: 15 (30%)

Compatible: 18 (36%)

Incorrect: 17 (34%)

What else it does: Not much besides tempo and key analysis. Its preference options for adding BPM/key to the file name, as well as different ID3 tags, are great.

Price: $58 US for Mac or Windows

Correct: 7 (14%)

Bpm And Key Analyzer

What else it does: MixMeister Fusion is a full-feautred, professional-level DJ software for creating and editing DJ mixes or DJing live with a digital audio workstation-style, timeline-based interface. A couple of the many notable features include mixing up to 8 tracks as once and support for VST effects.

Price: $329.95 for Mac or Windows (key detection also available in Mixmeister Studio for $199.95)

Correct: 15 (30%)

Bpm And Key Detector

Incorrect: 21 (42%)

Bpm And Key Analyzer Free

What else it does: RE2 is an intelligently designed DJ utility made to use both and preparation for and during your sets. Besides tempo and key detection, it includes tap tempo and a software MIDI keyboard for you to work out BPM and key yourself, normalizing,time/pitch shift processing, live audio input analysis, key lock and more. You can save Mixouts, where you comment on mixes between particular songs. In addition, the MixShare website hosts a large harmonic mixing forum and a database of track information for hundreds of thousands of songs shared by RE2 users.

Price: Free for Mac or Windows (donations encouraged)

IMPERFECT HARMONY

It should be said that this test can only provide a look at the accuracy of each of these programs relative to each other, rather than an assessment of the overall accuracy. I was surprised at the number of incorrect readings for each program. I’ve seen some other similar tests with higher percentages for Correct and Compatible readings, so there may some particularly difficult songs in my test batch. /download-game-deer-hunter-pc.html.

However, we can tell that that Mixed In Key 4 has the better numbers by a razor thin margin. MixMeister only gave out minor key results for some reason, which really hurt its stats.

Because Mixed In Key, BeaTunes and Rapid Evolution were statistically comparable, it comes down to which of those programs’ other features you want, as well as perhaps price.

My personal favorite is Mixed In Key, because it gives your results in the alpha-numeric Camelot System values — which is easier for mixing — processes files quickly and gives you some good options for how you want the key and BPM information to be added to the file name and to the file’s tags. However, it doesn’t do much more than key and BPM analysis, and it costs the most of the top-performing three.

As a free download, Rapid Evolution 2 gives you many interesting features besides key and tempo detection. and it makes up for not giving you the Camelot System numbers (User error: you CAN get the Camelot Sytem numbers in RE2 in the Keycode field.) You can look at only songs that are in a compatible key range, as well as similar in style and tempo.
