More frustrating than helpful...

AmazingSlowDowner consistently crashes. Even as we speak I’m trying to play a song on it because I have a show Saturday and have a bunch of songs with key changes to learn, but have to keep pulling up AmazingSlowDowner and let it tell me numerous times it failed to play the song. Or it just won’t do anything when I select a song to play. One of the only times I can “practice” is when I run in the morning. It’s been a huge headache. It will get through a song, not move onto the next, I’ll have to stop and totally interrupt the flow of everything, open the phone, try to get the next song to play, half the time it still won’t play and I’ll actually have to restart the entire phone to get it working again, when other normal music apps will just keep playing through each song. I don’t think it’s worth the money I paid. I have never bought an app this expensive and don’t like the fact that it crashes, freezes, and doesn’t work right. If it was a free app, I wouldn’t care as much because I didn’t have to pay for it. But $15? I’d almost rather get my money back, but conversely I need a way to practice these songs with the key changes and this is the only app I know of that can accommodate. If there is an option to actually download the playlists with their changes to avoid all this that I’m not seeing, forgive me. But I’ve searched and don’t see anything like that here.

Speed is not working

I love AmazingSlowDowner but the part that’s not working is the whole point of AmazingSlowDowner . The speed bar does not affect the song whether I slow it down or speed it up, the speed stays the same. I’m trying to learn jazz/blues improv and need to be able slow some sections down so I hear the exact notes being played. Please fix this!

really great + request's

AmazingSlowDowner is wonderful and when it was shown to me and recommended to me by a friend I got it and was worth every penny. Within the first 20 minutes or so, was able to learn a phrase from a song I could never figure out for years. Especially good because i'm completely blind and rely on iOS' voice over and was happy to learn that AmazingSlowDowner was fully accessable to me. All in all a stupendous app and would highly recommend. Just a few requests.
- add flick gestures for voice over users
- a function to adjust the quantity a slider will change
- The ability to change the name of imported files that are just a jumble of numbers and letters
Thanks again for a great app :)

Trumpeter transcriber from solos to horn parts

This is an awesome app, everything I needed and more. Cutting my transcription time 3 fold. I would have rated it 5 stars only for the problem Apple created with its MP4 proprietary crap not allowing music you've purchased through them being used with ASD. I hold Apple/iTunes the blame for this. I paid for the use of the music I should be able to use it as I please. I've sent the request as ASD suggested to Apple requesting they allow ASD access to iTunes purchased music!

More than worth the price!

More than worth the price! Truly a game changer! I tried cheaper options and their interface looked more interesting, but those looks were deceiving. Those others were difficult to effectively manage and really buggy. ASD proved to be “amazingly” intuitive, easy to organize what you’re learning, and completely bug free. You do have to “own” your iTunes music that is imported, and they have to be downloaded to your device—Apple won’t let you work in other programs with their music otherwise. I do pay for Apple Music, so I have to individually purchase those pieces I decide to accompany on my banjo. But that is a very small added cost for the time ASD saves when learning the song. Besides having quick and easy control of pitch and speed, the setting of focused sections of songs is very easy—I was setting focused loops on the fly the first night of practice using ASD. Each loop only took seconds to create and are automatically organized under a disc looking icon linked to the song. Having the loops organized with each song like that is one of the many details that make using ASD intuitive and effective. I do not typically leave reviews—less than a half dozen made in my lifetime across all platforms—so this review is a sign of how impressive and helpful AmazingSlowDowner truly is. Thanks for this great product!

It truly is Amazing!

I think this is the first review I have ever written. Normally I wouldn’t go out of my way, but AmazingSlowDowner has truly revolutionized the way I teach and practice. Everyone who plays an instrument needs AmazingSlowDowner! Also, a couple of days ago, I was having trouble with AmazingSlowDowner , which was probably due to Spotifys servers being down. I emailed the company and got a quick response and shortly the problem was fixed. It was at that moment, I realized how much I depend on AmazingSlowDowner! Worth everything you pay and more!

Best of the best

This software is unquestionably the very best that I have ever used to slow music down and change the key. It has at least tripled my ability and speed to learn new fiddle songs.

I learned of this software when playing in NY from a musician who worked for Fender. He said it was his best kept secret as a session musician.

I’ve tried others, but this one is the best by far for me.

Great app for singing practice

I'm a classical singer who has been relying upon this wonderful app for years. If I have a recording of a song's accompaniment, AmazingSlowDowner can transpose it so I can try it in different keys, or I can slow down passages to work on them (and set it up to repeat that section over and over again while I practice it). It is very reliable, doesn't take long to download and update, and I have nothing but admiration for the developer.

The most useful app ever!

AmazingSlowDowner helps tremendously to learn my parts
gradually working up the tempo. It allows me to loop difficult sections and recall them to play along until they’re smooth. Several loops can be stored within a song and played at variable speed. AmazingSlowDowner seriously improved my ability to work on my part independently of the band rehearsal time. We can now spend our time working on dynamics instead of figuring our timing.

Must-have Tool for Producers and Songwriters

I’m a music producer and songwriter. ASD is an excellent tool to organize bounces of mixes/songs I’m working on. I’ll airdrop an MP3 to my files folder on my phone, and then I use ASD to access it while I’m on the go to listen in different keys, tempos, and select specific loops. I use AmazingSlowDowner literally every day to listen to things I’m working on. iTunes would not do the trick, it’s not as seamless and doesn’t have the functionality I need. Thanks so much for making such a great product!

Amazing App!

AmazingSlowDowner existed for years on the pc platform, I used it for a decade to help learn guitar licks. About a year ago I learned that they ported to iOS and I downloaded it immediately, as I’m now learning drums. AmazingSlowDowner is invaluable not just because it has the same functionality as the desktop version — it has even more functionality AND it’s portable!
The only function missing from the pc version on AmazingSlowDowner is the ability to mute the frequencies where the vocals reside, but that’s a minor sticking point.

Best tool ever

I’ve used AmazingSlowDowner to learn a ton of songs. I’m a professional singer, musician and actor and this has served me very well. Perfect for singers who need different keys than the originals, and also to learn the words. I like to speed each song up to practice the lyrics faster so that when I sing it at tempo I can think faster than the words. If you’re looking for a tool to practice songs as a singer or instrumentalist, there’s no better app to do it. I never leave reviews. This one is special. Also, to the developer, please don’t ever abandon it, I need it! Thanks!

Must have app for guys (and gals) like me! 😎

This is easily one of the most useful apps I have purchased for learning tunes. I originally purchased this primarily to slow down songs but I now use the pitch option almost as much as I use the slow down option. I wish I had a looping option back in my youth rather than having to pick up and drop the needle on the record over and over. Great app and I have had absolutely no issues on my iPad or MY iPhone.

Daily use as a guitarist!

AmazingSlowDowner is simply ... “Amazing”. I use it constantly to slow down difficult Guitar passages AND then loop them so I can practice long or short sections. It is perfect for learning solos or riffs with difficult timing. The sound quality is terrific though (as another reviewer mentioned) some distortion becomes audible at very slow speeds, but it is not intense distortion and doesn’t prevent hearing what you are trying to learn. Because I am using either MP3 or AAC, I’m sure the distortion is due to file compression. Having said that, there is zero doubt that I am a better guitarist because of AmazingSlowDowner. I would buy it again in a heartbeat due to its ease of use and solid feature set!

THIS IS AS CLOSE AS YOURE GONNA GET

ok so how many of these have you downloaded just to be told you cant use apple music songs? well this works, only it meets you half way. no pitch or eq adjustment of apple music songs but the slow down sounds INCREDIBLE. any music file will load. the looper function is great because it can gradually get faster every few repeats which is perfect for learning new riffs. but yeah the algorithm for speed is a solid 10/10, while the pitch adjustment is more like an 8/10, which is still better than most. its worth the 15 bucks for the pro version. it works so smoothly and only looks kinda dated. a new updated UI would be nice.

Many uses

AmazingSlowDowner is so awesome for practicing and learning new parts. I remember the old days when you had to slow a tape down the transpose back to the correct key. No more of that with ASD. Even at 50% sped it maintains the original pitch. You can adjust the tonal settings to highlight the instrument your trying learn in the mix. Once you get the hang of it it’s super easy to set a loop to repeat over and over in perfect time. Another great use is finding a few bars of a drum part from a song you’re learning and looping it to practice over. Once you get the section of whatever you’re trying to learn dialed in you can save it and open it right back up where you left off. Finally, being able to open tunes from your iTunes library is amazing!! (This wasn’t so easy in earlier versions). I soooo wish I’d had AmazingSlowDowner when I was a jazz sax major in college trying to transpose recordings. I love everything about AmazingSlowDowner.

Fantastic app for music students

My vocal teacher suggested I get AmazingSlowDowner. And it has been so incredibly helpful. I am able to load in songs I’ve purchased and slow them down enough so that I can really study the singers vocal technique. It’s also been where I keep all my vocal exercises in a playlist so that I can just run through them every day. I also appreciate that I can slow down some of the more difficult ones that I can’t do at full speed already.

In addition, being able to take any song that I like and change the pitch is a huge help!A lot of the songs I like are sung by men and out of my vocal range. This way I can change it to my range and sing along.

Lastly and maybe most importantly is I needed help with something and they got back to me immediately! With a personalized clear answer that really helped me take advantage of features I wasn’t sure how to use. Highly highly recommended please support this company they are great and the product is great.

Simply Amazing

As a lifelong cover musician who has always played by ear, my life has always involved tuning my guitar to whatever tunings the original artist used. Not a huge hassle, but not hassle-free either. The Amazing Slowdowner has changed the game for me. I only wish this technology had been available when I was in my 20s, but I’m sure glad to have it in my 50s. AmazingSlowDowner not only allows you to slow music down to the extreme for the purpose of learning, it also allows you to tune the source material to your guitar, rather than tuning your guitar to the source material. Playing in a band that typically detunes guitars by 1/2 step, this feature is extremely handy. And while similar technology has always suffered from digital artifacts when using time compression/expansion or de-tuning algorithms, AmazingSlowDowner suffers very little digital artifacts distorting the sound. Tuning a whole song down a half-step produces a high enough quality source audio file, that you can use it over a PA as an intro with no real noticeable drop in audio quality.

As advertised!

Great for slowing down difficult percussion passages. Some distortion is present at very slow speeds, but it's still completely workable. Didn't read all other reviews, but if you come across a "protected" file that won't import - there's a way around that too.
————-
Checking back in on AmazingSlowDowner in 2018. I’ve used it religiously for the past 6 1/2 years and it is STILL amazing. Someone complained that it was too expensive at $15 (a few years ago). Are you kidding me?? For the serious musician that works at getting things right, AmazingSlowDowner is priceless. Given the amount of use, time saved, and difficult passages learned - I would in retrospect have gladly paid $50 for this. Regular updates keep it working smoothly. I also dislike that it won’t import protected songs from iTunes (which I HAVE paid for). Not AmazingSlowDowner designer’s issue - it’s Apple’s. But you can simply burn the songs you want to slow down onto a CD as a regular mp3 file, then import that version into your ITunes and import it into ASD. It’s an extra step, but again, if you’re serious, it works and is worth it. THANK YOU, app designer - this has been a godsend!

Music AND Language! At the same time!

I have had AmazingSlowDowner for years. At first didn’t use it much but then moved to China where I slowed down transcripts so I could copy the pronunciation (along with the tones). I am now using it to slow down songs so I can learn the rap portion in Chinese as well as instrumentals! Well worth the money I bought it for. I have dropped pitch of songs too. Does a good job of changing key without too much distortion.
