Logic 9 Logic 9: Do I need iZotope Radius any longer?

    Hi fellows,

    because I am from Germany I have to wait for Logic 9 about 3-4 weeks.

    Till the end of August iZotope Radius can be bought for $199 instead of $399.

    In the new Logic there are the new elastic audio features.
    So are the new features good enough or do I need still the best algorith, iZotope Radius?

    Everyone wants to save money, so please give me a good advice.

    Elastic audio sounds fantastic and has a far better UI than using an offline algorithm like Radius.

    However, Elastic audio only stretches time. Radius stretches pitch as well. There are no new pitch features in Logic 9.

    So it depends what you need. If you do any pitch shifting, I'd still recommend Radius.

    i bought Radius mainly for quick destructive region editing and it does it really really well.

    I'm thinking about buying Radius for LP9, but now that LP9 has flex time editing, which is restricted to time based editing, with no pitch-editing capabilities, I wonder, what are the chances that LP9 will offer flex-pitch-editing features in a future update to LP9 ?

    I think Radius is a good tool to have, but even at the special price of $200. it is not a cheap tool to add to LP9 just for pitch editing. I sure hope Apple/Logic Pro team will offer some form of flex-pitch-editing in a future update, without having to wait for the next version of Logic Pro (LP10). Which IMHO could take another couple of years to materialize.

    Any guesses if this will happen in a future LP9 update ? or should I not waste time, and just go ahead and buy Radius for pitch editing ?

    I also would like to know if Radius will allow to fix pitch of an audio source material (monophonic) on input, for example to restrict input to a specific scale, or to alter the overall tuning on input up or down x amount of cents ? or is it only possible to edit pitch after the audio has been recorded into LP9 ?


    PS. This is my first post on this forum, LUG forum is a very helpful resource for Logic Pro users, I'm glad I joined.

    thanks for the info
    o.k., thanks, too. The same opinion I have, too. But I waited for pitch-shifting hopefully to get it in Version 9. But again, not implemented.

    So perhaps I will buy it. Waiting and waiting cannot be the right decision.
    One advantage of Radius now. You can use it in Soundtrack, too.

    Greets and thanks for all advices.

    I bought it this month because of the sale and to have it in the tool box. I did demo it first and compared each feature to Logic 9's built in time and pitch shifting ability. I was actually very surprised at how well Logic did with pitch shifting a full mix track up and down, but, Radius was still better. In terms of changing tempo I thought Flex did a great job. So for me it was all about the pitch changing ability. There have been times where people want to change keys. In the past I've used Pro Tools for this and a plug in called X-form, or Pitch n Time but I'm very happy to be able to do it all in Logic now.

    Until today I was thinking that I would be using elastic audio instead of Radius. For many jobs I probably will, but today I was working on a saxophone track.

    There were quite a lot of dodgy artifacts that were being added, it was better than L8 "Follow Tempo" but in the end I found that radius did a better job, albeit much slower as there were quite a few changes to make as I'm quite good at playing the saxophone out of time.

    Thanks for all replies here.

    I have decided to buy it at the 31.08.09.
    Till next week I will have the money.

    Nice I got ALL your remarks.

    Fixing pitch at the input is not a good idea. Analyzing the material and changing the pitch needs time. The signal will be delayed and you might experience some artefacts and gliding notes, depending on the amount and speed of correction. It is possible but if you don't get it right, the take is lost. You can never fix such a damaged recording afterwards.

    Second, the Logic TimeMachine, Radius and Pitch 'n Time (from Serato) are not made for diatonic correction. Both alter a whole region or a selected part destructively, according to several parameters. They recalculate the audio signal and change it's data. What you are asking for is rather the domain of Melodyne and Autotune.

    Perhaps a few people tested Logic 9 now a little bit deeper.

    Is it still necessary to buy Radius?
    I tested Flex and it worked good for me.
    I never tried the pitch in Logic 9, but read somewhere it would work well in Logic 9, too.

    I do not want to pay $199 if I would be satisfied with the Logic 9 integrated stuff.

    So please give me a fast device because at the beginning of October I would pay $399 for Radius again.

    Nevertheless I will order it tomorrow.

    If you need to change the pitch of polyphonic sources then yes. If all you want to do is change the timing then it might be debatable. You can download it and try it yourself in demo form. I haven't used mine much yet but am glad I have it as I used X-Form for pro tools quite a bit and know that they licensed the radius algorithm. X-form worked great for changing pitch. I've only used Radius to change keys on an acoustic guitar track so far and it did a good job. Sorry I can be of more help.

    That was enough help, really.
    Downloaded and tested this afternoon.

    Thanks for all replies and opinions here.

    Conclusion: bought it 15 minutes ago.

    Well, speaking of this topic I was checking out Radius in L9 as I really haven't used it much. I started to worry as it didn't seem like it was processing the test mix, and Logic looked frozen. Then, I found this at and thought I'd pass it along:
    After clicking the Process button in Time Machine with the "Radius Mix" algorithm, Logic Pro appears to freeze.


    Logic Pro does not show progress while processing a time-stretch or pitch-shift, so it may appear that Logic is frozen. It is not actually frozen, Logic is just not showing the progress of the operation. To address this problem, we created an application which shows the processing progress.

    Before processing a file in Logic Pro, open the "iZotope Radius for Logic and Soundtrack Pro" application located in:

    Applications/iZotope/iZotope Radius for Logic and Soundtrack Pro/

    After clicking the Process button in Logic, a progress bar will appear in the iZotope Radius for Logic application."

    I was patient and the file was pitch shifted no problem.

    That's interesting, as it seemed like normal behaviour to me. I don't ever recall seeing a progress bar for any time & pitch machine operation prior to installing Radius anyway.

    Just tried it.... oh and there it is, in the bottom of the Radius app.. Still doesn't seem to represent what is actually happening. There's a long delay between that progress bar completing and the completion of the task.

    Thanks for the heads up! :)

    I used it today for a client to transpose a whole stereo mix down 400 cents (4 half steps). It did a great job with no noticeable artifacts.

    I wonder why he didn't want you to make it 5/4 and change the lyrics.

    He did...actually, it was a Karaoke track that he was singing for some corporate event. It wasn't a "real" project. The point was that the software does a good job. 2 years ago I had to do some key changes of some finished raw tracks prior to mixing and used the x-form plugin for pro tools. It worked great. I read that x-form uses the Radius algorithm so it's nice that I don't need pro tools for this (or anything really), even though I have it.
