View Full Version : How does this sound?
Greg Miller August 6th, 2013, 04:40 AM I don't recall ever hearing the term "broader" applied to audio... not sure what you mean by that.
If you mean "wider frequency range" then it's a tossup: "Test 1" has more high frequency information, "test 2" has more low frequency information. The range is roughly the same, but the frequency balance is different. Visually, the slope of the line is different.
"Muffled" relates to attenuated high frequencies = "High frequency rolloff." Less "bright." Less "crisp." Think "treble control turned down" in simplistic terms. Are you agreeing with that definition of "muffled"?
If you can, play one given clip through a typical stereo system with the tone controls set "flat." Then turn down the treble control and hear the difference... that is what I would call "muffled." Or listen to someone speaking to you in person. Then have them speak through a few layers of terrycloth towel... that is "muffled."
Are you sure the numbering didn't get confused at some point? The "test 1" file I downloaded has the talent counting backwards, and definitely has more high frequencies.

OK, just double checked. The numbering is correct. I am just describing what I hear incorrectly. #1 is just missing something, like some frequency is missing (again, i am probably describing it incorrectly). I see what you are saying #2 being more muffled I guess. #2 does not show the same characteristic as #1. Overall #2 sounds better than #1 to my ears (but still not that good)
Greg Miller August 6th, 2013, 07:50 AM If we're going to discuss audio, using words, it will help if we use accepted terminology.
Test #1 is not missing "some frequency." A given frequency describes a particular tone or musical note. For example, the frequency 440 Hz describes the pitch of the musical note "A" above middle C. The frequency 261.6 (roughly) describes the pitch of middle C. Lower frequency > lower note on the scale. The bottom notes of the piano are below 50 Hz. Low frequencies = very low notes.
Test #1 is not missing anything... everything seems to be there. But Test #1 has less content -- lower amplitude; less level, or volume if you will -- in the lower frequency range (in this case, below about 800 Hz) when compared to Test #2.
Test #1 also has more content -- more amplitude; more level -- in the higher frequencies (in this case above about 1,000 Hz) when compared to Test #2.
Beyond that, it becomes less straightforward. Test #2 has more content in the lower end of the spectrum... it sounds "warmer." It also seems to be lacking somewhat in high frequency content... it sounds "muffled." Test #1 has more content in the upper end of the spectrum... it sounds "brighter" and has better intelligibility; but it also somewhat lacking in the lower end of the spectrum... to my ear it has an unpleasant "harsh" and rather nasal sound (that can be a combination of the speaker's voice, the characteristic sound of the mic, and the overall frequency response).
It's unfortunate that you are trying to learn sound "in a vacuum"... not a physical vacuum, but learn it without the presence of a person who can discuss this with you and play audio examples for you so that you learn what to listen for and learn the accepted terminology. Looking back, I feel extremely fortunate that I had mentors with good ears, good production chops, and one of whom had a very good EE background who could explain all the theory to me as well. I hope you can find a good mentor who can help you there in person.
Meanwhile, you say Test #2 sounds better to your ears. What system and components are you using for playback, and in what kind of room?
Jon Fairhurst August 6th, 2013, 11:00 AM Regarding wiring the Sanken for XLR and wireless use, check out my post here:
http://www.dvinfo.net/forum/all-things-audio/497102-sanken-cos-11d-sennheiser-g2-g3-systems.html#post1806609
BTW, I've read that TrewAudio will do the assembly and soldering to build this system, if you don't have a way to accomplish it yourself.
Kathy Smith August 6th, 2013, 01:11 PM OK, I tested both of my Sanken mics against each other. I am at loss here. Listen to these 2 samples. This is not really about the quality recording as I am still using my crappy wireless system but I was expecting both mics to sound the same since everything is the same on these 2 recordings. Let me know what you think.
Steve House August 6th, 2013, 03:45 PM Mic 1 has more depth and a bit of reverb, sounds like your previous post's Test5. Mic 2 sounds 'strained' and there's a lot more noise, similar to your previous post's Test4.

So what do I do? My two mics sound different. Basically I could tell that the levels on the second mic were way lower.

Turns out I've got some sort of interesting (to me anyway) cold-ish thing going on so I'm less sure what I'm hearing than I'd like. My *ears* have got some low frequency roll off going on, which I find perplexing.
But... those two samples sound quite different to me. From mics that expensive and with that reputation, I'd expect them to sound almost identical. You might want to discuss that with your dealer, IDK.

I am going to order the XLR adapter to test both mic recordings bypassing the wireless crap.

Greg, thank you for your detailed explanation. I was trying to wrap my head around it. I know it's frustrating to talk to me about this because I don't even know how to properly express myself.
I am basically listening to the recordings in my bedroom, haha, using Sony MDR-V700 headphones.
Greg Miller August 6th, 2013, 08:47 PM Kathy,
In my experience and opinion, Sony headphones typically sound overly bright, that is they have a somewhat boosted level through the midrange (let's say roughly 1,000 - 5,000 Hz) and high frequency (let's say roughly 5,000 upward) region. Especially the midrange is "hot."
That's fine if you're using them to monitor your audio while you're doing some field recording. They will accentuate little noises and unwanted sounds, alert you to their presence, and perhaps lead you to re-record the track making it better.
But that is NOT fine if you're using them to evaluate the overall audio quality of a track. They will take a track that is rather "muffled" or "muddy" like your Test #2, and boost the midrange and highs (exactly the part that is attenuated in the track) and make everything sound fine. Meanwhile, they will take a track like your Test #1, which is already a bit boosted in the mid/high frequency range, and boost that range even further, making that track sound overly bright, strident, call it what you will... and since that track is already a little weak in the lower frequency range, the Sonys will accentuate that problem. All in all, they will make Test #1 sound worse than it is, and make Test #2 sound better than it is.
By all means you need to get some other opinions. I suspect other folks will concur with my opinion about Sony phones. And I think a lot of folks will agree with my preference of Sennheiser "HD 280 pro" phones as having a much better balanced frequency response.
Also, I urge you to get to a reputable dealer and compare the two sets of phones, using some material you're familiar with (preferably something that was commercially recorded, so you can somewhat trust the quality). If you can hear the difference, that's a good start.

I do have Sennheiser HD 280 pro which I use at work and for in field recordings. For this test I just happened to evaluate the recordings at home.
Greg Miller August 6th, 2013, 09:13 PM Listen to those five tests again, using the HD 280s, and see if it changes your opinion. (It may; then again it may not.)

I will do so tomorrow. In the mean time I need to figure out what to do with my 2 Sankens that sound totally different.
Greg Miller August 6th, 2013, 10:09 PM Agreed. That surely must be very disconcerting. When and where did you obtain them? Both at once from the same vendor, or otherwise?
Kathy Smith August 7th, 2013, 03:56 AM Agreed. That surely must be very disconcerting. When and where did you obtain them? Both at once from the same vendor, or otherwise?
I got them both from B&H. Separate orders. I waited for them over a month because they were being sent from another vendor and one got lost.
Paul R Johnson August 7th, 2013, 04:31 AM Kathy is getting plenty of advice most very accurate and considered, but other information could be misinterpreted. Shure SLX is NOT crappy or the other words used in a derogatory manner. Video people who are sound centred often get very hung up and polarised on individual features. Other sound professionals have a broader acceptance and understanding that products perform and sound differently, but very often 'bad' in one context can be 'good' in others. I don't like Shure SLX myself, because I prefer Sennheiser, but I have hired in Shure, Trantec, Audio Ltd and Sony kit and would not object to using any of it. The differences are really split into two areas. Tonality and compression. Both are very subtle, and easily sorted afterwards. What causes the biggest problem is the misunderstanding of gain structure. The Shures have a very wide range of input level adjustment, and on the receivers, a wide adjustment to cope with the typical users. This means it's so easy to under-deviate the transmitter, and then need more gain from the receiver. The result is quite noisy audio. The SLX has good performance when the input gain is set too high, the audio limits quite gently without the brittle sound you get on other brands. Wireless gets treated like magic by many people, when it's not. When correctly set up, SLX along with the others, is quite capable of letting you hear very subtle differences between mics. It's a fallacy that X brand is always better than Y brand. There will always be differences, the same way as expensive preamps sound nicer (note, not better) than cheap ones. Expensive wireless systems are built more strongly, have less plastic, perform better in congested or interference prone areas, and last longer. They all use different companding systems, that either help or hinder the sound source if the receiver doesn't track 100% accurately. I have even heard real budget Chinese wireless systems that are horrible and plastic sound really good - I suspect no companding at all - and with a strong RF signal the audio was almost cable quality. Of course, it suffered badly as the s/n went down - but audio wise, it was good.
Very rarely can we say any audio product sounds bad. They just sound different, and the difference can be critical. Kathy needs to train her ears, and there's a danger here that words used to express our opinions can be misinterpreted. Sound terminology is always flawed. X sounds more 'airy' than Y. We all know what that means, BUT is my 'airy' the same as yours? Is kathy listening on full range studio monitors, near fields, headphones or what? If our comments are made based on what we can hear, can Kathy hear the same things? This is more important than labelling products as good or bad. Some of us can squeeze excellent results out of the 'wrong' equipment, and other repeatedly produce rubbish with amazingly expensive kit.
Jon Fairhurst August 7th, 2013, 11:45 AM Paul, are you sure that you were using the SLX product, rather than some other Shure wireless product?
We bought a couple of transmitter/receivers and two wireless monitors here at work. We used them for live audio that went over an internet video link and as a backchannel to the remote person. We were using the stock lavs with the transmitter/receiver. We were quite disappointed with the lack of high frequency carriage. The speech was a bit difficult to comprehend using the system (before going through the web link.)
The marketing of the SLX seemed to be for a mid-priced solution for live rock bands. That makes sense. The quality isn't pristine, but the SLX seemed to be reliable and usable in a loud, live context.
I was later asked to update our audio system for company meetings. People had problems comprehending the speakers in the cafeteria room with ceiling speakers. I didn't even consider using the SLX. It would have been functional, but wouldn't have improved comprehensibility. We went with a Sennheiser EW100, which exceeded our needs for a live speaking event.
Personally, I wouldn't consider using the SLX for recorded video, except for low-quality, functional stuff. I found the Sennheiser EW100 to be a big step up from the SLX and would be happy to use the Sennheiser in pro settings, unless really pristine audio is required.
Is the SLX crap? Not at all. It's reliable and hits a price point. It would be usable for a local rock band. It's marginal for live speaking events. I'd consider it to have amateur/consumer quality for recorded video. It's certainly not a match for the quality of a COS-11D, which I use with a wire and find to sound beautiful.
In Kathy's example, I'm confident that it's the weak link in the chain.
Our two SLX systems are sitting here collecting dust. I keep them available as "mobile intercoms", but that's about it. We should have gone straight for the Sennheiser.
Daniel Epstein August 7th, 2013, 01:54 PM I will do so tomorrow. In the mean time I need to figure out what to do with my 2 Sankens that sound totally different.
Hey Kathy,
Variants between mics do happen and the chances you have a deficient one is possible. Also not sure but are they the exact same model? I have several Voice Technology mics and even though they look the same they are actually different models. Sanken seems to have the same kind of differences.
SANKEN MICROPHONE CO .,LTD. | Product [ COS-11D R-RM-*1-*2 ] (http://www.sanken-mic.com/en/product/product.cfm/5.1107700)
Maybe you have two different models. I have two Sanken Heads which have subtle differences as well. I am in NY City so we could probably test a few things locally if that helps.

Daniel,
The mics are exactly the same. I e-mailed Sanken and they are taking the mic back. Thanks for the offer to test the mic. I will just ship it back to them and see what happens. I am also waiting for the TA4 to XLR adapter to arrive so I can see if I can improve the overall quality.
Daniel Epstein August 11th, 2013, 10:02 AM Sounds like you have arrived at a good solution. Nothing wrong with returning the equipment to the source if you have issues. Let's see what happens with the new stuff. Offer still stands if you need more problem solving
