Where your hours get sucked up needlessly
You’ve listened to the song five times and you still aren’t sure where the cut should go. It’s late, you’re zoomed all the way in on a waveform, trying to get two pieces of audio to align without sounding choppy. You and your kids love a certain song, except for that one word. You would take out more repetition from within the song, but every cut you make takes too much time to blend back in, time you don't want to spend on nit-picky music details.
Dancers have enough to overcome without having to battle their own music. Every routine deserves music that measures up to the work that goes into it, and creating pro-quality song edits doesn’t have to take a huge amount of time.
Shorten
Edit any song to routine length.
Remove a verse, tighten an intro, keep only what the routine needs. Smart678 maps the song’s sections and snaps every edit point to the beat, so that your dancers perform with music worthy of your choreo and the work they put into it.
Clean
Scrub out inappropriate lyrics.
Grab the sponge tool to remove words while leaving the music perfectly intact. You can also mute all the vocals with one click for an instant instrumental.
Speed
Change the tempo.
Speed a song up or slow it down so that your dancers aren't rushing the beat. Smart678's sophisticated algorithms keep drums crisp and vocals clear. Make your changes in percentage or tempo increments.
Made by a guy who edits songs and mixes music for choreographers professionally
Squirrel Trench Audio has been making music for dance studios since 2010, and our soundtracks have been used in more than 25,000 routines worldwide. Since 2015, Morriss has helped administrate the Music Help for Dance Teachers group on Facebook, which means he understands the music challenges dance teachers face daily.
Most teachers do their own music, and they don’t have the tools or techniques that professionals use to create perfect song edits quickly and easily. Smart678 is the next best thing to having a professional audio engineer at your side to guide you.

Questions, answered
How long does it take to learn?
About one song. With anything new, it takes a few minutes to get oriented. After your first song, most people get cruising on it. That’s because Smart678 analyzes the tempo, locks the beat to a grid, and maps out the song’s sections for you. For many songs, you never have to zoom in to find the transient of the waveform, and will get it to routine length in just a few minutes.
“”
What kinds of songs work best?
Songs with a steady beat, which is most of what dancers perform to. Smart678 finds the tempo analyzes the song structure, and keeps your edit points on the beat. Free-time songs can still be edited by hand.
What files can I upload?
MP3, WAV, M4A, and AIFF. Downloads come back as a high-quality 320 kbps MP3 or a 44.1 kHz / 16-bit WAV, ready for the studio and the stage.
Do I need to install anything?
No. Smart678 runs in your web browser. The heavy lifting happens on our servers, so it works on the computer, tablet, or phone you already have.
How do credits work?
One credit unlocks one song. From then on, that song is yours to edit and download without limits, and re-uploading it never costs a second credit. Paid credits keep for seven years.
Is my music public?
No. Your songs and your edits are private to your account, unless you want to share your edit points publicly.
