Applications to discover the name of the song by sound or by singing
Hearing a song in a store, at a movie, or on the car radio and having no idea what it is is no longer a problem. Simply point your phone's microphone at the sound source and, in a few seconds, the app will return the name, artist, album, and a link to listen to the entire track.
However, there is an important difference between identify by sound and identify by humming, And that's where most lists confuse the reader. Recognizing a recording playing is one technology; figuring out the song from your voice is another, much more recent one, and few apps do it. Below, you'll see exactly what each of the five apps can do.
By sound or by singing: what's the difference?
When the music is playing, the app generates a "fingerprint" of the segment—a map of frequency peaks over time—and compares it to a database of millions of recordings. It's a very precise, but rigid method: it identifies that specific recording. Therefore, a live version, a remix, or a cover rarely matches the original recording.
Humming requires a different approach. Since your voice has none of the timbre of the recording, the system only needs to extract the melodic line—the sequence of intervals between the notes—and compare it to the melody of the songs in the catalog. It's much less accurate and depends on you getting the melody reasonably right, but it works even if you're singing out of tune, because what matters is the relationship between the notes, not the absolute pitch. Only two apps on this list do that: SoundHound and the Google app.
Benefits of using music recognition apps
Besides satisfying your curiosity, these apps keep a history of everything you've identified, which in practice becomes a list of discoveries to consult later. Several also send the music directly to a playlist on Spotify, YouTube Music, or Apple Music with a single tap.
Another benefit is the material surrounding the track: synchronized lyrics, translation, artist information, album the song was released on, and concert dates. And all of this works partially or very lightly offline, without consuming significant data—an identification uses only a few kilobytes.
5 best apps to find out the name of a song
All of the following apps are available in the official app stores for Android and iPhone and identify songs for free.
1. Shazam
Listed as Shazam: music and shows, It's the most accurate app in its category when music is playing. Today it belongs to Apple and is completely free., It does not display ads and has no in-app purchases. — something rare. Identification takes only a few seconds and works well even with moderate background noise.
An important clarification: Shazam doesn't identify hummed songs.. It requires the original recording to be playing. However, it has an automatic background identification feature that recognizes what has played near you even with the app closed, and a mode that identifies audio from another app on your phone—useful for discovering the soundtrack of a video. It also features synchronized lyrics and direct uploading to playlists.
2. SoundHound
O SoundHound It's a veteran in voice recognition and remains the best option when you only remember the melody. It identifies both the recording playing and the sung, whistled, or hummed portion you make — just hold down the button and produce a few seconds of melody.
The accuracy of the humming mode isn't guaranteed and often drops in quality for lesser-known songs or when the melody is very different from the original, but it's the most effective method in this scenario. The app also features synchronized lyrics and search history. The free version displays ads and offers an optional subscription to remove them.
3. Google App (Search for a song)
O Google app, The app, already installed on most Android phones and available on the App Store for iPhones, has its own melody-based identification feature. Tap the microphone icon in the search bar and choose "Search for a song"—then just hum, sing, or whistle for about ten to fifteen seconds.
The system returns a list of likely results with the percentage of match, instead of a single answer, which is helpful when the melody is approximate. It also identifies recordings playing normally. It's free and, since the app comes pre-installed on the device, it doesn't require any installation. On many phones, the same feature is available through the system's voice assistant.
4. Musixmatch
O Musixmatch Dynamic Lyrics It is, first and foremost, the world's largest collaboratively maintained collection of song lyrics. It identifies the song that is playing and then displays the synchronized lyrics word for word, with a translation into Portuguese.
It's the right choice when you want not just the name, but to follow and understand the lyrics. It also integrates with streaming services to show the lyrics over what you're already listening to. It doesn't identify songs by humming. The free version has ads, and some features, such as real-time translation and Android Auto mode, belong to the Premium plan.
5. Deezer
O Deezer: Listen to Music and Podcasts It's not a facial recognition app, but it has one built-in: the SongCatcher, The app, accessible through the search function, identifies the song playing near you and adds it to the service's catalog.
The advantage is continuity: you can identify and listen to the entire track without leaving the app, saving it directly to a playlist. It's the best option for those who already use Deezer daily and don't want another app on their phone. It's worth remembering that the free version of the service has ads and listening limitations, and that offline mode is only available in Deezer Premium.
Tips to increase your chances of success.
When the music is playing, hold your phone close to the sound source and focus on the chorus or a clean instrumental section, avoiding the first few seconds of the track and moments with spoken conversation. Loud noise and highly reverberant environments significantly reduce the accuracy rate.
In humming mode, sing the chorus, maintain a steady rhythm, and produce at least ten seconds of melody—short snippets almost never work. If nothing comes of it, try another part of the song. And if no app recognizes it, the recording may simply not be in the catalogs: live versions, DJ remixes, and independent tracks are the most common causes of failure.
Conclusion
If the music is playing, Shazam is the fastest and most accurate, and it's free with no ads. If you only remember the melody, SoundHound or the "Find a song" feature in the Google app are the way to go—these are the two on this list that accept voice. Musixmatch works when you need the lyrics, and Deezer's SongCatcher is useful for those who already use the service.
It's worth having two installed: one for recordings playing and another for those moments when the music only exists in your head. All can be downloaded for free from Google Play and the App Store. Suggestions for other apps? Write to [email protected].
