Vocal tuning
I have a microphone going into my computer and I am recording my voice. I see the reverb, echo and various options for changing the sound of my voice. Is there an option to auto tune my voice so that it absolutely not flat. I realize that it would help if I was a better singer but I'm just curious.
Thanks for any help!

flex pitch is not good enough when tuning vocals
introduces distortions and destroys the original sound what is the reason?
competitive tuning programs do not have such a problem.
Do something with this pleaseNow I know why no one has responded to my query.
I found this article that we could start with to answer this question, since I saw that there were a fair number of views for this question.
It basically says, there is no set industry standard for pitch deviation. Timbre makes a difference. What is generating the the tone makes a difference. According to this article there is much more generosity when it comes to pitch deviation with vocals than with instruments and especially soft instruments. And that a lot depends on the the context; what notes and sounds are around any note in question can make the note sound more or less in tune. Also emotional singing makes us (even seasoned musicians) tolerant.
It seems that they are saying, as with one of the generally accepted tuning systems, vocals are forgiven +10 cents (sharp) through -15 cents (flat), in general, including vibrato.

Here is the discussion where I found it.

I'll keep this question open in case anyone else has anything to add. Please let me know if you interpret this article differently.

Vocal tuning in GarageBand on Ipad
Hey guys, new to this so bear with me. I'm trying to find out if there is a way to tune vocals in GarageBand for Ipad. Any help would be awesome. Thanks.
Do you have headphones with the mic/controls on it? If you have a set for the iPhone, plug them into your iPad to see if you can record that audio. If you can, then we can look into why it can't record the other way.
If you don't have those, I'll try loading GarageBand on my first iPad and see what happens. -
Final Cut Studio 2 issues with some AU Audio Plug ins
Just installed Final Cut Studio 2. When trying to open the program, every time it reaches the audio filters loading part of the load, it crashes. It's seeing Celemony Melodyne, a vocal tuning plug in, and then it just stalls and crashes. All attempts to remove Celemony Melodyne from my computer haven't seem to make any difference. It keeps trying to laod that plig in. Is there any way to tell FCStuido 2 to NOT look for certain audio filters(plugins) during the loading process?
You can use a free Audio Unit manager app (like AudioUnit Manager) or even better, use Jon Chappell's Plugin Manager tool (which is part of his excellent FCS Maintenance Pack)

Is anyone having trouble with vocal glitching in playback?
Listening back to vocals with the full band, one vocal track sounds weirdly garbled/distorted (almost auto-tuned sounding, not over-driven). But when I listen to it "solo," it sounds normal. This only happens on certain tracks and I can't seem to fix it after it starts happening. Flex pitch is not on.
Most recently, I upped the reverb a little bit on the track and it started making the weird sound. I moved it back down to the original level and it was still giving me problems. The first time it happened, it was on a different track WHILE I was recording vocals.TTry this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Check your settings. The iPads have a small switch on the right edge. It can be used as a rotation lock to keep the screen from automatically reorienting itself as you move around, but you need to have the tablet’s settings configured properly. That same switch, right above the volume buttons, can also be set to function instead as a mute button to silence certain types of audio.
If the switch is set to work as a mute button, you can change its purpose to “screen-rotation lock” by tapping the Settings icon on the home screen. On the Settings screen, tap General on the left side, and on the right side of the screen flick down to “Use Side Switch to.” Tap to select Lock Rotation or Mute to set the button’s function. Even if you set the side switch for your preferred use, you can still mute the Mini or lock the screen. Just double-click the Home button, and when the panel of apps appears along the bottom edge of the screen, flick the row from left to right with your finger. Tap the icon on the far left side of the row to either lock the iPad’s screen or mute the iPad’s alerts, notifications and sound effects. Music, podcasts and video are not muted unless you turn the volume all the way down.

HT6019 Automatic Tuning in Garageband 10.0.1
Hello, Can someone please help me.. I do a lot of vocal recording using Garageband 6.0.5 and a usb mic, when editing finished recordings i like to add some reverb and amongst other filters I use the automatic tuning slider that used to appear in the audio region box on the bottom left hand side of the screen.
Can someone please tell me where to find this feature in Garageband 10.0.1???
Im by no means an expert with Garageband, But I would think I've a good understanding of most of its uses.
Hope someone else has had the same problem and can point me in the right direction,
Thanks, PhillPhill85 wrote:

Can Garageband measure pitch on a vocal waveform?
I've just recently discovered that Garageband has an autotune feature that will take a recorded vocal waveform and alter it to transform off key notes to on key. I would like to know if there is a way in Garageband to analyze a recorded vocal waveform and identify the pitches and/or note names in that track. I would like to see when and where a vocal gets slightly sharp or flat so the singer can improve the performance w/o resorting to autotuning.
You can use the "Tuner" to show how far the pitch is off:
Single out the vocal track.
Set the LED display to the "Tuner" (you should see the tuning fork).
Play the song.
The tuner will show how far the pitch is off.

How can I create harmony using one vocal
I'm trying to learn how I can... Instead of having 3 people sing or one person sing all three parts, I can sing one part and somehow create the other 2 parts making harmony...??? I was wondering if it was Hermode Tuning but...???
You can pitch-shift copies of tracks, with pitch-shifter or vocal transformer, or have the one track send to several busses with these plugs inserted, but really, doing it this way will tend to sound more like an effect than real harmonies, (even if you delay the shifted copies)
To get authentic sounding harmonies, you need too record each part. (even recording each one in the same part and then shifting those tracks will sound better than working off the one recording) -
Ho do I enahance Tuning and "Limit to Key" in Logic 8 like in Garageband?
I use enhance Tuning and "Limit to Key" in Garageband to make that synthetic vocal sound that locks the vocals on key like they do in todays Hip Hop and dance music, but the big question is...
how is that done in Logic 8?With the Pitch correction plugin from Logic's "pitch" folder. With a bit of tweaking/abusing the plugin you should get what you want.

Follow Up...Vocal Mixing Approach
I've been kicking around possibilities in a different thread with some very helpful people
http://discussions.apple.com/thread.jspa?threadID=2386425&tstart=0
Now, I'd like to implement what AT THIS POINT, I think may be my best way to approach the issue of getting my vocal mixes good.
First, I am going to go back to using my mic the way I had in previous recordings. That is, using the large windshield that came with my SM7, that helped with a lot of plosives etc. Also, I will apply the bass roll off and NOT the presence boost. Presence boost seemed to give too harsh highs. I can EQ later if need be. Flat will be easier to start with. As far as pre tracking, this is about all i can do, since I know my recording levels and all are good, and i don't have any other equipment besides the SM7 and the DUET.
Next, I would like to know y'alls take on "NORMALIZE". I usually have not ever normalized my vocal tracks. The last one I had issues with a lot, I actually DID normalize, So, perhaps I WON'T in the future. I'm gonna open up a meter for monitoring. Prolly the Multimeter. I'm going to go in and for the sake of time, only do some manual edits to the volume envelope for the REAL bad guys, those that stand out clearly in my ears. Maybe do a quick check for anything that is REAL quiet too, boost that a little manually. Problem is I don't know how much to boost or lower. Can I see with the meter what the overall average db is, and see if I have a loud part that hits, say -6db and the average is around -12db, so I'd just lower that part by 6db?? and vice versa for quieter parts.
Now, the fader is controlled by the volume envelope so if I do automation I will lose control of the fader for my levels, so should I insert GAIN plug or just use an output gain on one of the inserts I'm gonna use anyways. Either way, at this point I will set the relative levels. Just a quick setting to start off with.
Now I believe I can apply this plugin
http://sounds.wa.com/audiounits.html
Thanks Ericksimon!!
Looks like a nice tool, similar to what I was looking for but not too cumbersome. I have not gotten a chance to try it out or see how to use it properly.
So at this point, I think I should have a really steady volume level going on.
Now I am not sure about the whole compression thing. I have come across several options. First though, do I want to do any EQing at this point??? before I add compression or after?? There are two points I would want to use EQ, one is to tame any out of control frequencies and 2 would be to shape the overall tone of the vocal. I suppose I could EQ for any bad frequencies first, then do compression and whatnot, then EQ at the end to slightly shape the sound if need be.
Anyways, compression. The Multipressor worries me a bit. I've used it with nice results on instruments and sampled audio, but not on vocals. Also, the downward expansion looks cool. I don't usually have any problem with too much noise, but I guess that's a problem i just never knew I had!!! I just try to track with as little gain as possible while still achieving a usable recording level. Then I get increase the gain later without having a lot of noise on the recorded track. Also, the multipressor would address my Highs in my voice jumping out at times. If I could just compress the Highs and not so much the lower frequencies. That might give me better results than JUST compression the whole spectrum equally.
The OTHER option, maybe, would be to use the DeEsser. I can compress a specific frequency range, but I don't think it has multiple bands. So, I couldn't really get any compression going on for the other bands. But I was thinking about the DeEsser in tandom with a Noise Gate instead of the Mulitpressor. This may be a little easier, but I think I might want to have a full spectrum compression, but be able to compress certain "trouble" frequencies more or less.
So I think I should be done at this point as far as levels and all that go, perhaps if I was to use EQ to color my track a bit, but that is gonna fall in with applying REverb and Delay or whatever else I want to add flavor. WHICH IS A WHOLE nother thread. After mixing about 13 tracks in logic now, I still can't find a setting that I'm comfortable with for my voice. Every recording seems different so every time i have to do something quite different. And every time i feel like it's the first time!!!
Anyways, how does my approach at this point look??
Holy crap,.....I didn't realize I had written that much. My god, If anyone replies you are truly a saint.Bee Jay wrote:

Never do it. Absolutely pointless.
I think if it doesn't hurt anything I WILL because I think it helps me when doing manual edits so that I have a point of reference that is somewhat consistent throughout multiple audio regions
Now, the fader is controlled by the volume envelope so if I do automation I will lose control of the fader for my levels,
This is a good point - in general, send the output of a channel to a bus/aux channel. You can now automate one, and use the fader on the other to offset the levels - doesn't really matter which, although I prefer to automate the channel fader to smooth out the signal before hitting the aux wher the compressor is.
I am not real familiar with aux channels, I've tried using them but didn't understand the send amounts and how it was affecting the signal. If I put the send amount at 100 does 100% of the signal get passed to the fader then. So in your example, I would definitiely want to set at 100. As of now I simply used the gain control on the compressor or whatever plugin was last in the chain, I think that should not be any different in the sound....
The Multipressor worries me a bit. I've used it with nice results on instruments and sampled audio, but not on vocals
I wouldn't use it unless there is a definite reason to use it. At this point, you don't sound sure why you are using, and thus are unlikely to use it effectively. So don't over-complicate and use something simpler - there are plenty of good sounding compressors around, if you don't like Logic's.
well what I did is looked at the problem frequencies that I had corrective EQ'd and made that one band,,,,from say 700-1200, then made the other two bands as 0-700 and 1200-18000 or whatever. I didn't touch the low band, but I applied compression slightly different for each one of the other bands. I think it turned out much better than I expected, but I really don't know that I needed much compression anyways......the manual automation, rider plug and EQing had the signal going to the compressor pretty good already. It's amazing how much better a compressor sounds when the signal coming in isn't pure garbage!!!
I just try to track with as little gain as possible while still achieving a usable recording level.
What levels do you record at?
I believe the settings on my Duet are at about 56-58 usually when I record. This puts the input signal usually bouncing around between -24 to -12 db. I heard that was a good range and leaves lots of headroom. I use Ind. Monitoring level to crank it up so I can record at this level, otherwise it's too quiet to hear over the beat. I like to perform with lots of volume. These settings seem to work well, and NO i don't have a noise problem. Actually after alll the compression and everything was said and done. The "silent" parts between phrases or words were actually pretty much dead silent. So that seems to tell me my gainstaging is correct?
Also, the multipressor would address my Highs in my voice jumping out at times. If I could just compress the Highs and not so much the lower frequencies. That might give me better results than JUST compression the whole spectrum equally.
Maybe, but I still think it's overcomplicating things, although it's hard to say without knowing the recordings. if you have particular sections which are harsh, the common technique employed by the big guys is to split the vocal ("mult") into multiple channels for the appropriate parts, so you can EQ and treat the parts separately. Some producers will even go so far as to automate or mult individual syllables in a vocal phrase, although that is extreme.
yeah, haha, It already took something like 4 hours last night to do what I did. I broke down and manually automated nearly every phrase/syllable in the song!!! Boy, that was work. But, the results were quite apparent. Even taming the out of control stuff, it gave life to the stuff that used to get kind of lost in the mix. I been reading the manual to get some easier shortcuts and stuff for editing automation, so that should cut some time a bit. Also, I'm not gonna be recording much more backing tracks I don't think. If I do, I will probably just copy the automation from the first "Lead" track to the backing track. I have gotten a little more comfortable using reverb to help fatten up my vocals.
So I used manual automation edits. Rider Plugin. Corrective EQing. Multipressor. "Color" Eqing. And Finally SilverVerb.
Sounded much better than before. And really I only spent about an hour or 2 more than what I had originally spent battling with plugins that couldn't correct a bad input. So good in good out and you know the rest. And like I said. I accidentally erased most of the automation I did, then saved then quit. Didn't realize I did that. Oh well. I'm learning -

thanksHi,
the plan you posted has the cost of 2300, i.e. 2300 single-block reads or equivalent number f multi-block reads. Even if none of the blocks is found in cache, 2300 reas shouldn't take more than a couple of minutes, beacause for most of the hard drives available today a disk read is typically within 5-10 ms.
This means that if there is a problem, we will never find out about it by looking in the plan. And it's quite likely that there is, in fact, a problem, because the plan contains a bunch of nested joins, and the cost of each nested join is directly proportional to the cardinality of the previous nested loop. I.e. it suffices to make one bad mistake in estimating the number of rows coming fom one of the nested rows to screw up the entire plan and get all remaining estimates (including the total cost of the query) completely wrong.
In order for us to be able to tell more, we need to see the plan with rowsource statistics, and please don't forget to use tags to preserve formatting (use the preview tab to make sure the posted plan is actually readable).
Best regards,

HOW TO: Post a SQL statement tuning request - template posting
This post is not a question, but similar to Rob van Wijk's "When your query takes too long ..." post should help to improve the quality of the requests for SQL statement tuning here on OTN.
On the OTN forum very often tuning requests about single SQL statements are posted, but the information provided is rather limited, and therefore it's not that simple to provide a meaningful advice. Instead of writing the same requests for additional information over and over again I thought I put together a post that describes how a "useful" post for such a request should look like and what information it should cover.
I've also prepared very detailed step-by-step instructions how to obtain that information on my blog, which can be used to easily gather the required information. It also covers again the details how to post the information properly here, in particular how to use the \ tag to preserve formatting and get a fixed font output:
http://oracle-randolf.blogspot.com/2009/02/basic-sql-statement-performance.html
So again: This post here describes how a "useful" post should look like and what information it ideally covers. The blog post explains in detail how to obtain that information.
In the future, rather than requesting the same additional information and explaining how to obtain it, I'll simply refer to this HOW TO post and the corresponding blog post which describes in detail how to get that information.
*Very important:*
Use the \ tag to enclose any output that should have its formatting preserved as shown below.
So if you want to use fixed font formatting that preserves the spaces etc., do the following:
\ This preserves formatting
\And it will look like this:
This preserves formatting
. . .Your post should cover the following information:
1. The SQL and a short description of its purpose
2. The version of your database with 4-digits (e.g. 10.2.0.4)
3. Optimizer related parameters
4. The TIMING and AUTOTRACE output
5. The EXPLAIN PLAN output
6. The TKPROF output snippet that corresponds to your statement
7. If you're on 10g or later, the DBMS_XPLAN.DISPLAY_CURSOR output
The above mentioned blog post describes in detail how to obtain that information.
Your post should have a meaningful subject, e.g. "SQL statement tuning request", and the message body should look similar to the following:

I'm sure that if you follow these instructions and obtain the information described, post them using a proper formatting (don't forget about the \ tag) you'll receive meaningful advice very soon.
So, just to make sure you didn't miss this point:Use proper formatting!
If you think I missed something important in this sample post let me know so that I can improve it.

Randolf

can't reproduce, does it still look unformatted? Or are you simply kidding? :-)

PS: Just noticed that it actually sometimes doesn't show the proper formatting although the code tags are there. Changing to the \ tag helped in this case, but it seems to be odd.

Need help in tuning a procedure
DECLARE
CURSOR Cur_sub_rp IS
SELECT A.SUB_ACCOUNT, B.PH_basic_srv,B.PH_Salesman,A.SUB_SSN
FROM STG_SUB_MASTER_MONTH_HISTORY A, STG_PHN_MASTER_MONTH_HISTORY
B
WHERE A.SUB_ACCOUNT = B.PH_ACCOUNT (+)
AND A.MONTH_ID = B.MONTH_ID ;
TYPE t_values_tab IS TABLE OF cur_sub_rp%rowtype ;
values_tab t_values_tab := t_values_tab() ;
BEGIN
OPEN Cur_sub_rp ;

EXIT WHEN Cur_sub_rp%NOTFOUND ;
END LOOP ;
CLOSE Cur_sub_rp;
FORALL i IN VALUES_TAB.first..values_tab.last
INSERT INTO SUB_PHN_1 VALUES VALUES_TAB(i);
commit;
END;
The tables used here has 9 million records each.
The total process takes around 19 minutes.
Need your help in optimizing the process.i have tried using
Create table as SELECT A.SUB_ACCOUNT, B.PH_basic_srv,B.PH_Salesman,A.SUB_SSN
FROM STG_SUB_MASTER_MONTH_HISTORY A, STG_PHN_MASTER_MONTH_HISTORY
B
WHERE A.SUB_ACCOUNT = B.PH_ACCOUNT (+)
AND A.MONTH_ID = B.MONTH_ID (+);But still taking long time(apprx 15 min).
so used this...
help me in tuning the query in either of this.
DECLARE
CURSOR Cur_sub_rp IS
SELECT A.SUB_ACCOUNT, B.PH_basic_srv,B.PH_Salesman,A.SUB_SSN
FROM STG_SUB_MASTER_MONTH_HISTORY A, STG_PHN_MASTER_MONTH_HISTORY
B
WHERE A.SUB_ACCOUNT = B.PH_ACCOUNT (+)
AND A.MONTH_ID = B.MONTH_ID (+);
TYPE t_values_tab IS TABLE OF cur_sub_rp%rowtype ;
values_tab t_values_tab := t_values_tab() ;
BEGIN
OPEN Cur_sub_rp ;
LOOP
FETCH Cur_sub_rp BULK COLLECT INTO Values_tab
LIMIT 1000;
EXIT WHEN Cur_sub_rp%NOTFOUND ;
END LOOP ;
CLOSE Cur_sub_rp;

I am using my Digi003 to record vocals. I have my MIC (SM57) in input 2 of the digi. WHen I create a new audio track and set it to input 2 nothing happens. I have tried to change mics and cables and nothing works. Is there a trick. I should be able to hit record and should hear sound right?
So frustrating!Did you select the device in the audio preferences of Logic?
Did you arm the track to record before hitting record?
Not sure if you've done either of these things as you didn't mention them in your post.
Good Luck! -
Real Instruments, Enhance Tuning, Enhance Timing, Etc?
Hi,
I am having trouble getting to the Real Instruments, Enhance Tuning, Enhance Timing, area of GB3.
I see the window partially, but not enough to move the sliders, while seeing there placement..
I'm sure there's something I'm unaware of to get the full view, and I've snapped a screen shot to show what I'm talking about, if anyone is interested..
Thanks For Any Help,
EricHang-
I have a work around I kind of stumbled onto..
http://members.aol.com/unkie/GB3-pict-2.gif
After you select the Real Instrument track you'd like to correct the pitch or timing of, you hit the "I" for track information, then you can click on the region arrow,(?) and the Enhancing area opens up properly.
Check out the picture linked above, and below I will place the before shot link..
The preference not coming up seems to be linked to using iChat, believe it or not..
I read it here in the forum.
If you open iChat, and then Garageband 3, your preference pane may not open up, until you reboot your computer.
Strange but true..
HangTime, Thanks for "Hanging" in there with me through this dilemma..
Take Care,
Eric

For Mom who needs little: Old mini or new mini?
I am upgrading my Mom from a 1994 Performa to a Mini, but I am on the fence as to previous version for $400ish or new version for $500ish. I want this to be as low budget as you go for a new mac. If it was a $3,000 mac I would get newer, but for $100
