@AudioMasterclass replies to @davebullard: It is true that stems sourced from the multitrack are a great mixing study tool. This however is probably better for studying performance and arrangement. IMHO.
@skesinis: From a mathematical and programming point of view, it’s not surprising that the mixed result of the individual stems can be identical in a lossless way to the original. While they can use a Fourier analysis with some other complex algorithm to try and separate the frequencies of each instrument and the vocals, after having all the separate channels and the original at the same time, you can tweak the multi channel samples slightly in such a way to match exactly the originals when mixed together in the exact volumes they’re saved.
This however, wouldn’t necessarily make them good separations. All it’d do, would be to simply have some kind of separate frequencies channels, which when mixed together give you back the original. Determining which harmonics are also part of the original instruments before the mix, that’s what makes a really good software shine.
@mcpribs: Software like these are a marvel of modern technology! What a joy to be able to”save” poorly produced band projects from years (and technologies) gone by. Rip sounded great. Thanks!
Also, I like your song. Well done!
@taidee: I'm no music maker, so I'm just blown away by what can be done with software here.
@donclingan3925: I would like to see a video with your opinion on the Harman frequency response target.
@AudioMasterclass replies to @donclingan3925: I expect to cover this at some point. Whether I'll come to any conclusions...
@donclingan3925 replies to @donclingan3925: Its just ive many headphones buds but picked a pair of samsung akg buds plus they follow the profile exactly and im blown away. Just for work they always get destroyed im a builder and didn't like the sound at first but i find myself picking them up before some stuff that costs so much more the codec is old now but they just sound almost balanced which for 30 pounds is amazing it made me look into harman found it fascinating am currently adding to the royalties you not getting listenening to your stuff its good pal very good
@donclingan3925 replies to @donclingan3925: i am not going to play anywhere without your permission but i would like to remix this i will send you a copy as soon as finished for your approval if that is ok. I respect artist rights which big tec doesnt anymore
@donclingan3925: I really like the words in the track just played it to my new partner and the beats brought back soul to soul vibes. I would use it for remixing tracks for DJ sets be good ripping a vocal and mixing it over a different track entirely. love the channel spent many years working in pa systems thanks
@jimhines5145: While both sound pretty darn good, I do still occasionally hear artifacts which sounds like phasing to my ears. I think this is why Giles Martin sent the stems to actual guitar amps in Studio 2 for the remixing of Beatles 62-66. To try and hide the artifacts. Do you agree?
@AudioMasterclass replies to @jimhines5145: Seems like a good idea given the context.
@Eurovision-OLD: I love using RipX DAW for restoring the sound on my old (or newer) posts of Eurovision songs. Anything broadcast before the digital age would always have some sort of compression, and now I can add a bit of dynamics into those songs again by working on the bass or drums/percussion to make it sound more vibrant. I'm a total amateur, but I'm having a lot of fun with it!
@spunkthecombo: Cool.
@theguy4310: Everyone commenting and this YouTuber have bad or deteriorating hearing
@scottlowell493: I've wanted to do this with various Rush albums and their notorious lack of low end.
@DJStanSteel: I DJ using ‘Virtual DJ’ software and can use stems on the fly. Takes about 15 seconds to put the track into 3 parts. It’s not great and has some artefacts in the sound but it’s useable. Stems mixing is becoming huge and most DJ software can do this now. But some ain’t that great.
@alterknacker58: Very inspired by APP … ;)
@jips123: Nice try, but we need the software (MAL) the Beatles recently used. The song and production btw is a poor copy of Alan Parsons Project.😅
@darryldouglas6004: Ha ha ❤ I love it! 80s synth pop. 🤩
@richardvanenteren2745: I held on well before you started singing but that was not too bad for me and I never expected to see your rather neat speaking voice😬😉.
@RudeRecording: I was just listening to the remixed Beatles Red reissue and the clarity was amazing! I did hear artifacts similar to the ripped samples that you played on the drums but the improved clarity was astounding, especially since many of those tracks were recorded on a 3 track tape machine.
I do have uses for that software and I suspect that it was used already on the Beatles 2023 Red/Blue release.
@ignatzmuskrat3000: Moises has a long way to go. And after 6 months of use, it doesn't seem to be getting any better. Kinda settling for second or third best in AI. The future, is now. In, a nutshell.
@ramilopez6921: Mystery software sounds like "Moises" the basic version.
@andrii4545: You can do anything! Just believe in yourself!
@imqqmi: It's impressive that software can extract so much from a stereo track! I'm not really into creating music but I can imagine it's interesting for people who are interested to dissect a track and see how it's mixed. Also for those who want to create rearrangements for different instrument arrangements for covers/bands/karaoke etc it could be handy. There's sometimes a song that I like except for often one annoying thing that I'd like to remove or replace. For example in the song Colors by Stella Jang the snap sound is just a tad too harsh, or in Equinoxe pt5 that rasping sound that starts fading in around 20s in on the right, it's nice for a few seconds and then it starts to annoy me.
Or some tracks that has a good theme in it, a nice instrumentation but is ruined by overbearing percussion. To get those tracks from almost perfect to perfect.
Who knows, with AI at some point, all instruments can be extracted at high fidelity and instruct the AI to remove or adjust certain elements in the track. But I know about the downsides to that of course, it'll be difficult to maintain a track and it's original creative intent, aside from the ownership and copyright issues.
@volsteh: waveform 12 has stem separation built in
@ac81017: Three chords A, F#m and E.
You have a very nice and pleasant voice.
@AudioMasterclass replies to @ac81017: What's good enough for Status Quo is good enough for me.
@retromograph3893: This is just marketing….. why not compare to Izotope RX , spectra layers or some other similar tool …..
@AudioMasterclass replies to @retromograph3893: Maybe if you'd watched the video you'd know that I did compare it.
@retromograph3893 replies to @retromograph3893: I watched the whole thing! ...... why don't you name the other software? Something smells a bit fishy if you don't ....@@AudioMasterclass
@gilberth_: David, soon you will be making a last-beatles-like song.
@AudioMasterclass replies to @gilberth_: Hang on… I haven’t done my own ‘Free As A Bird’ yet.
@s_r_v: Lemmy's bass from Hawkwind 'Lord of Light'
@AudioMasterclass replies to @s_r_v: Yes that would be a pleasure to listen to isolated.
@stevengagnon4777 replies to @s_r_v: @@AudioMasterclassreally like that Lemmy, Hawkwind era. Especially the live concerts Either you get an unbelievable Lemmy driven experience or sometimes a mess. Lemmy is Motorhead !
@s_r_v replies to @s_r_v: It took 45mins on my slow PC the result was ok, I don't know what I was expecting, but I can't think what I'd use it for now, perhaps it would be good just to remove vocals and produce a karaoke track...
@philiplane3533: Try Spectral Layers 10. It beats RipX hands down. You also get piano and guitar stems separate and can even separate drums down to kick, snare and other. I've used it for several projects since buying it. I was able to recover a decent drum track from a kick, hat and overhead track when the other files were missing. I've also rebalanced a couple of mixes. I was also able to extract a synth solo from a Prog track and turn it into midi a score using Melodyne and Cubase for a learning aid for someone. Both programs work as extensions within Cubase which makes workflow really pleasurable.
@yvesfrancoisritmo: What i want is to seperate the orchestra on L'Alibi (1937) - the Bobby Martin orchestra - from the actors talking in the movie. Uncertain if much of the music is loud enough in background from the speaking - but i would love to have a software to do that and hear that great band.
