Low Input Level

I've come to the conclusion, based on the many other forums I've visited....that the Macs are terrrible for recoding with an external microphone. The input level is too low. I (along with so many others) have used M-Audio preamps, USB microphones etc. and connected them properly and still cannot get a decent audio track (voice only) using ANY app on the mac. I, for example bought the M-Audio Podcast Factory which even comes with it's own microphone and literally have to speak less than 1" away from the mic to get any amount of volume. I'm trying to decide whether to purchase a digital recorder such as the ZOOM H2 Recorder ($250.00) to solve this mac deficiency.......

I don't think "lots" of people have a problem with low levels. Only a few who don't have proper equipment or don't really know what they're doing.

Do you have the Phantom Power turned on? (needed to drive the Rode NT). I use an Alexis Firewire with an M-Audio Nova condenser mic (a cheap version of the Rode NT) and if I crank the input up too high it clips all over the place. The point being the problem is very likely elsewhere, not in the software or the Mac.

Hi Scott,

You've completely misunderstood how it works.

What you're saying is the equivalent of saying "My TV is terrible because it only plays boring TV shows."

As a recording device, the Mac is an empty vessel. It's "level agnostic." It only records what is fed into it by your external hardware. It's actually a similar technique as the H2 recorder or any digital system: an analog sound is converted into a stream of digital information and stored on a hard drive and manipulated with software. In the H2, the mic, preamp, conversion, and storage all occur in the device. In the Mac or a PC, the mic, preamp, and conversion typically happen outside of the computer via an interface; the digital stream is fed to and stored in the computer where it can be manipulated with software. Because the mic, amp, and conversion happen outside of the computer, that actually gives you the opportunity to use much better hardware and get much better results than an all-in-one like the H2. (The point of the H2 is portability).

The problem you're having is because your mics and preamps - your external hardware - is not good enough or loud enough for your expectations.

In the past several years, there's been a ton of low cost external hardware produced, cheap interfaces, USB mics, etc. This is all good because it lowers the price of admission, and anyone, using free software like GB, can produce music, often with excellent results.

However, there's a reason why people still pay thousands of dollars for microphone preamps, for digital converters, and microphones. There's a world of great gear out there that musicians, engineers, producers and studios use every day to create fantastic sounding recordings in conjunction with their computers. But they're not using USB mics and $150 interfaces. USB mics and $150 interfaces get you in the game, but they're not in the same league.

You would have the same problem if you hooked up a crappy USB mic to any computer.

You could also get great results if you hooked up a fantastic mic and interface to any computer.

Sadly, if you want to elevate the quality of your audio, you need to invest more in better hardware.

I have no idea about your experience, but experience also matters. Not that the scalpel doesn't matter, but it's the surgeon, not the scalpel, as they say. People who know what they're doing can make lesser gear sound better than people who are clueless but have top of the line. While your crappy preamp is limited by its own crappiness, do you know everything there is to know about digital gain staging in order to milk every last bit of audio goodness out of it?

Settings? The only settings I see are the "Sound" in System preferences, where the mics can be selected and "Audio Midi Setup" where I can select inputs. All settings are accounted for. Power to the USB microphone comes from USB and the M-Audio product is supposed to be a preamp. Not sure that I am missing anything here and if you search all the other forums, I am far from alone with this problem. I have been using macs since the "Plus".

OK, guess I got stuck buying fisher price gear and have to speak 1" from the mic or yell at 1 foot. I can accept that and see that maybe preamplification is the issue here. (I must ad that the built-in mic picks up my voice from several feet away but I'd like a higher quality recording...using a mic) Let's assume I want to make a simple podcast using GarageBand. My voice on it's own track. If I am to buy something that will actually work, is there a reasonably priced solution or should I buy something like the Zoom H2 Recorder and import the audio into GB?

You don't need expensive equipment to do a podcast. You need to decide what you want out of your equipment an work on that. Your setup now seem like a typical narrator type setup where the mic only picks up what is directly in front and no room noise. You seem to want to pick up everything in the room like the built in mic on your mac. You also need more gain from your pre amp.

I just sold a presonus inspire that had plenty of gain much more then the Fast track I using now maybe something like that. And I like onmi condenser mics for a picking up large areas. Maybe some has suggestions.

I have a H2 and it works as a usb/mic/interface it has a three position preamp switch and can be set with limiting. May be a good idea also.

If you buy something like the H2, you are re-buying components you already have (the storage, the software). People buy the H2 and that kind of thing because they want a convenient portable recorder they can set up anywhere. It's convenient, and it works, but you can get much better quality results buying a decent microphone and interface.

If you think about it, the H2 is around $150. Subtract the cost of storage and what you're left with doesn't buy a lot of 1) microphone, 2) preamp, 3) converter, 4) software. That said, if you like it and it's adequate for your podcasts, then go for it! Maybe you'd want the portability anyway.

However, to answer your question directly, yes, I think you could buy something reasonably priced that would work well, particularly if all you're recording is voice for podcasts.

You've already tried a USB mic, don't know which one, but I know people are using them for podcasts with good results - maybe you just need to buy a better one (not that a USB mic will ever be that good, but there are a few out there that aren't fisher price).

Here's a page from Sweetwater with some popular models:

As for buying a mic+interface that's reasonably priced - that depends on what you consider "reasonably priced." Speaking of Sweetwater, you could call and talk to a sales rep (but don't let them talk you into buying something you don't want to buy!) or post your budget here or at Gearslutz ("low end theory" forum) and see what people say.

My USB mic is an APEX 182 (can't even find it on their site) and was around 60 bucks, looks impressive! I did find on their site however, software to increase the gain, but unfortunately it is only for Windows machines.

The M-Audio setup I have is basically the Fast Track unit with "Podcast Factory" instead of "FastTrack" on the front. A related product to that is this:

May be the solution.
Yes, it is only my voice I want to record, nothing else in the room and istevus, your guitar recording sounds amazing!

I'm having the same problem with low input levels. I'm setting up a client/friend's iMac 24. He's got a couple of Rode NT1 mics going into an Alesis iO|2 USB interface. The Alesis iO|2 has mic pre's built in. With the input gain on the Alesis iO|2 set as high as it goes without clipping, and the overall gain on the Alesis iO|2 set at maximum, the REC level in GarageBand barely registers on the horizontal psuedo-LED meters. The waveforms on test tracks we record are very small. I'm used to getting a very hot signal that goes into the red, then backing off until I see that the passages with the highest gain don't clip anything.

I opened AUDIO/MIDI utility, and chose Alesis iO|2 as the input. When I do that, the box showing settings opens. The three faders representing the volume settings M, 1 and 2 are all grayed out. I understand that the proprietary software in the Alesis iO|2 takes control away so that the Mac's software can't set the input "properties".

So, am I simply stuck with this? Why wouldn't a commercial product like the Alesis IiO|2~not~ be able to deliver a hot signal to the Mac's audio software? I can take a weak track, import it into Peak, then boost the gain to where it's just shy of clipping, then import it back into GarageBand but that seems a bit silly. Apparently, lots of people have problems with low input levels in GarageBand. I've seen responses like, "Well, it's better to record at too low a level to too high a level." That hardly addresses the problem, and is certainly not an answer an engineer could accept.

Yes, poflynn, the phantom power is on. These condenser mics won't function at all without +48v power.

Is the Alesis iO 2|6 not considered "proper equipment"? As for people who "don't really know what they're doing" that's why I'm here, asking for help, even though I've been recording music since the '70's.

While your Alesis Firewire audio interface can deliver signals to your Mac that can clip "all over the place", on my Alesis iO 2|6 ---with all the output knobs pinned--- I can't get a signal to register higher than about 25% of the psuedo VU meter, never coming even close to clipping. Since the only components of my system are Rode mics, the Alesis interface and the Mac, where "elsewhere" could my problem be?

Jul 22, 2009 7:58 AM in response to Jack Hobson-Dupont

It sounds like you know what you're doing, recording-wise. I'm still a relative newbie myself so I can't say for sure why you're not getting the levels you should be. I can tell you, as I'm sure you know, that more people use Macs than PC for music production and that many a CD-quality (or near) have been recorded using Macs and even GarageBand.

I've never used USB (having been told early on that Firewire is superior). As to whether that would be keeping your levels low I don't know. Wait, first you said IO 2, which is USB. Now you say IO 26, which is Firewire (the same unit as mine only with more inputs). Which is it? That could make a big difference. But either way, what do the meters on the Alesis register? Are those going red when the gain is way up?
