Slow down music without changing the pitch.

Overview

Amazing Slow Downer allows you to slow down music without changing the pitch.

If you're a musician who likes to learn new songs and techniques by listening to the same piece of music over and over but wish that the music could be played a little slower, then you'll enjoy Amazing Slow Downer. This program reads music directly from your CD-ROM drive and slows it down between 1% and 400% using a "time-stretching" method which does not change the pitch, regardless of the speed!

Most programs of this sort require you to record the music first. Not with the Amazing Slow Downer. It processes the music in real time - just insert the CD and press the play button. You may also play MP3, AIFF, and WAV files. Other features include increasing the music speed up to twice the normal rate, pitch adjustments in semi-tones at full or lower speed, and more.

What's new in Amazing Slow Downer

Version 4.0.8:
New:
  • Better support for movie files (.mov and .m4v)
  • Minor cosmetic changes including better support for "Dark Mode"
Bug fix:
  • App could crash when trying to play a missing file
  • Key command for the "Cue slider" didn't work when slider was set to the far end

Great little program when you need to slow down a musical passage. I don't use it too much anymore, but actually used it last night to slow down part of one of *my own* guitar solos so I could learn how to play it! lol

I have used this for some years to speedup hearbooks and other audio content. ASD was the best tool available; even at 200% the sound is easy to understand and and just slightly skewed. But very good slow-down / speed-up algorithm are nowadays available in many different video- video and audio players, like VLC, MplayerX and Vox. I have ditched ASD for VLC, which has in my opinion an even better speed-up algorithm, allows 4x speed up plus a more modern GUI; and is also free.

ASD is made for different purposes though. The fact that you can loop a part and then use the EQ to remove other instruments makes it easy to learn tricky parts of songs. You can also save those parts as files.

I use ASD, either the desktop or the iPhone version, daily to learn traditional tunes. I've tried the others that previous reviewers have suggested and I always come back to ASD. Ironically, the reasons I always come back are the same reasons that some don't like the program: The interface is not especially Mac-like, but it is perfect for ASD. Pretty much everything you need is displayed in an uncluttered, logical fashion in a single window. I find ASD very intuitive and easy to use. There aren't a lot of features like tablature, multiple markers and so on, but for someone who wants to learn tunes by ear it is perfect. Different users have different needs, and ASD probably is not the best choice for some. It is, however, the best for me. The only way to know is to download it and try it out.

As a cellist, I think this is a terrific program and highly recommend it. I am a long-time Mac user, and find the interface very intuitive and easy to use. You drag a trac from iTunes and then simply change the playback speed by adjusting the slide position. What could be simpler for dissecting a difficult passage? A great value for $45. Also, Rolf Nilsson of Roni music immediately sent me instructions for migrating my registered copy to my new Mac, the kind of personal service I was pleasantly surprised to get from the head of the company.

I tried ASD on a friend's computer and I am not amused. I am myself a computer expert on Mac (via PDP11 and Unix), a bass-trombonist, Jazz and Salsa arranger in my spare time. Musicians do not waste your time with a person who is a brilliant programmer but so so on as a developper of a users friendly interface. I am thinking to try and buy Transcribe! which is a very good program and not so expensive. That is my two cents. Have a nice day. Greetings from the Netherlands. Frank Rojer ***.. MSWFUJOWDFFYC I'm impressed by the quality with which ASD is able to manipulate pitch and speed. Of all the programs I've used, the sound quality on ASD is one of the best. From a user interface standpoint, ASD is nothing short of an attack on everything that is good and decent in the world. The UI is an unmitigated disaster. I honestly can't imagine how it could be much worse. For this, they have taken quite a bit of criticism over the years, and rightfully so. Someone at Roni must really love it though because they've had the same horrible turd of an interface now for years. The mind reels at how much more money they would make with a decent interface, and if they'd sell ASD as an AU and/or VST plug-in. The folks at Roni are geniuses in pitch manipulation and complete retards otherwise. Please, guys, PLEASE come into the 21st century!

Indeed, there are now many different apps available that are much easier to operate. I bought this 3 years ago, but within a year I'd sprung again for Capo, and I'm glad I did but kicking myself for paying for this mess in the first place.

I've been using this for years and never found it hard to use. Honestly, you don't spend much time in the interface. You load your track, find the part you want to study and set the speed you ant to play it back at. The interface is not all that horrible; you have your start and end points, the speed, pitch and balance, cue, etc. I've certainly seen worst GUIs! To me the bottom line is that the app works great, and is not hard to use. I set it and forget about it while I'm working on a musical passage.

My replay was really meant for MSWFUJOWDFFYC, but because of the way you quoted it, it ended up here. Still, it's not hard to use at all.

A very cool program, but i don't have enough use for it to buy. 8^( Can't say much about the user interface, myself since i haven't used it to the extent that problems leap out.

Developer: I would like to lend my voice to previous reviewers' calls for a major interface upgrade. There should be some way to access the iTunes playlists from within the program. Secondly, the windows should be resizable; in the sense of having corners that can be dragged. Furthermore, there is no way to search within larger playlist. Overall, there is way to much clutter and it doesn't feel Mac-like whatsoever. Unfortunately, since I feel that I am constantly fighting with the interface it kills the user experience for me. Like the last reviewer, I see the program being actively updated without the UI problems being addressed. On a positive note, the program is second to none at its primary purpose of slowing the track down and changing pitch. Developer, please do something. I am trying very hard to love this program.

Request to Developer: PLEASE FIX THE TERRIBLE USER INTERFACE, OR GET SOMEONE TO DO IT FOR YOU! The functionality is GREAT and unmatched, but the more I use this program the more I realize it's extremely user-hostile. Look at a program like WireTap Studio for an example. How about a waveform of the track so we can visually set start and stop points? There are so many problems, I can't begin to list them all. The playlist needs to be a separate window, resizable, sortable the same way an iTunes playlist is. USEFUL. I need this program to work FOR me. The developer updates it regularly, and regularly IGNORES these issues. please HELP US

Another musicians comment. Quicktime can't do what ASD can do. It's just not as easy to loop, have presets and so on. There's no Slow down types in Quicktime. This program is meant for TRANSCRIBING. (An art that most musicians don't do alot of these days... for some reason.) You can also practice along a section of a tune by looping a section at frame accurate resolution. This means that you can loop a section and nudge the start and end points just right so you can practice a section along with it in perfect time. As it loops back to the start point you can adjust it so it's in complete time so you don't break the flow of the pulse. If you don't know what I'm talking about pick up an instrument and try practicing a section looping in quicktime. Good Luck. In ASD, you can speed it up bit by bit without having to render it. Or try speeding it up in quicktime. Good luck since the slider is small and jumps in huge increments. Amadeus is NOT a TRANSCRIBING tool. Nowhere on the website does it say that Amadeus is great for transcribing. Thats because it's not. It specifically says "Amadeus Pro is a powerful multitrack audio editor...". ASD is NOT multitrack audio editor because it's not supposed to be. In actuality I shouldn't be comparing Quicktime with Amadeus with ASD because these three apps are in three different categories. If anything you should have all three of these pieces of software. Quicktime to pull the audio from a movie , Amadeus to edit out dialog and keep only the score, and ASD to transcribe the score easily. ASD is a musicians tool made to do musicians things. This is NOT a tool to make cool effects or to edit out a sax solo. It's supposed to help you hear sax solo at various tempos. Try transcribing "Koko" or "Shaw Nuff" by Charlie Parker (if you know who he is) and you'll quickly realize that Quicktime, and Amadeus don't cut it... because they weren't meant to do what ASD was meant to do.

Actually, Amadeus is a very good aid in transcription. So is sound studio. And even QT can be used. It's just that these program are not as dedicated to the task as ASD is. I actually bought ASD for a different function: I used it to adjust speed and pitch of loops and other sound samples for use in sequencing (something that DigitalPeformer, my sequencing software, doesn't do very well on its own). ASD's processing of audio is unparalleled. It sounds great, even with extreme changes of pitch and/or speed. Since buying ASD, I no longer use Amadeus for transcribing, and I'd highly recommend it to anyone who transcribes on a regular basis. However, that doesn't mean a casual transcriber can't make use of Amadeus, etc. simply because these programs don't exclusively specialize in this area.

buying the wrong tool for the job will make your job worse. Using ASD for time compression/expansion is a good/cheap way instead of spending hundreds in something like serato or protools. If you casually transcribe your money is well spent on ASD. The journey of 1000 miles begins with one step..... forward, not sideways.
