Cheap directional condenser mics for voice use - some ideas

Posted by admin |

I'm thinking of getting an affordable directional condenser mic for use as a boom mic but also as a general voice mic. It would be nice if it is switchable to different polar patterns. Ideally I'd like to pay around €50, but two of the below ones are more expensive.


Around €90. AKG C1000s MKIV The AKG C1000S is a classic condenser microphone, that gets a surprising amount of hate on the Internet, including from some people who have actually used it. The only mic I've seen receiving more hate is the Blue Yeti. Both mics are best sellers so they can't be all that bad. The AKG CS1000S Mk IV can run on two AA batteries besides 48V which is great, and it has switchable polar and frequency characteristics which also makes it more versatile.

Here is a Youtube example including rap. The Session with Blazewun - indoor dialogue AKG c1000 test - YouTube The rap is also recorded with it, and not just the monologue. The rap uses the hypercardoid setting.

AKG C1000 Battle - Indoor Dialogue - The Adapter Features - YouTube same guy again, now comparing all the modes: Cardoid, hypercardoid and presence.

Avantone CK-1

Around €150. Avantone CK-1. Rave reviews on the store sites. A bit on the expensive side for my budget. It gives you three different capsules and a shock mount included. Good.

This is the video I found wrt voice. It seems to have been lossily encoded into oblivion though: Avantone CK-1 Microphone Test w/Hyper Cardioid Cap Installed on Vimeo

Samson C02

Here we're coming down to €45 territory. Samson C02. Supercardioid characteristics and shock mount included.

Best microphone setup for indoor interviews?

Posted by admin |

Summary: The two options seem to be lavalier/lapel microphones or overhead boom microphones. Lav mics seems by far the easier option.

Curtis Judd talks about this a bit and seems to favoor boom mics. However he points out that so called shotgun mics have problems with room echo and are best used outdoors. For indoor use you can use directional mics without that shotgun tube. Hypercardioid is the description to look for, for highly directional mics.

Boom mic'ing is a lot of work and lavalier mics is a much easier option. If going with headset mics, plosives can become a problem, might be interesting to see if there is a good pop shield for headset mics.

One other option that could work would be to put directional mics below the subjects, at least if they are sitting down. But I think you want to place the mic within 50 cm or so of the mouth, which might be difficult. Still, it would be elegant to just have two mics, one in front of and below each subject's head, since that would very easy to set up.

Shortlist of audio interfaces of which I will select one

Posted by admin |

I currently have a 16-bit Behringer Xenyx 302USB, and I'd like to upgrade to 24 bit to get some more room under 0dB. I'd also lke to try out a large diaphragm condenser mic so I need an XLR, and I'd like to keep the ability to have a powered mic input for 3.5mm. Actually the Xenyx I have has a 12V XLR which is enough for the mic I'm looking at, so maybe better to start in the mic end and arrive at the interface end later.

I'd also like to have a recorder in it, since Android phones have problems with USB and Bluetooth has problems with, well, the Bluetooth standard which has no capability for good mic audio (maxes out at 16KHz sampling rate).

And since I prefer to do everything in post, more than 3 channels into the computer would be nice.

Apps to the rescue to record from USB on android?

Posted by admin |

I tried to record sound to a Motorola G5 through a USB sound card connected via an OTG adapter. Didn't work although playback worked. On a Nexus phone playback didn't work either.

It turns out USB sound card support is skimpy even in newer versions of Android.

One solution that is recommended on a forum is USB Audio Recorder - Apps on Google Play. The app has its own USB driver and their site shows support for a lot of phones and a lot of audio interfaces, including some really fancy ones.

But its free version available from their web site behaves lik a zip file on the phone, instead of as an apk, despite having the right suffix and being in the same folder as other working apks that can demonstrably be installed, downloaded with the same program.

I found also n-Track Studio Music DAW - Apps on Google Play but it wants to read my contacts. I'll see if I can turn that off and see how it behaves.

Best mics under €150 judging from the male soul sample at Thomann

Posted by admin |

These five microphones I selected from going through most of the sub €150 large diaphragm mics on their site listening on the male soul dry sample through my my laptop speakers, and then ranked the below five between themselves by using a Sony MDR-XB950 (a so-so) headset listening to the same sample. A couple of mics on their site did not have the soul sample and were ignored. No mics between €119 and €150 made the list, as can be seen below:

Rank Name Price Interface Comment
1 Samson G-Track Black €105 USB 16-bit Gorgeous sound, even truer than the C03U, but with a bit of personality (this has a different soul sample than the others)
2 Samson C03U €89 USB 16-bit Great sound, but with a weird distortion, which might be from my headphones still sounds very honest. Shines on the processed version, is best there.
3 Audio-Technica AT2020 €89 XLR/48V Slightly tinny but still great
4 Superlux E205 €38 XLR/12-48V sounds fantastic over laptop speakers but loses its luster in the MDR-XB950 headphones but shines again in the Sony MDRCD480 phones. As somebody said in the reviews, this mic sounds a lot better that ithas the right to.
5 the t.bone SC 1100 €119 XLR/48V weird wandering sound in headphones

Audio-Technica AT2020 USBi and AT2020 USB+ sounded worse than the XLR Audio-Technica AT2020 listed above.

Superlux E205USB sounded worse than the XLR Superlux E205 listed above.

The Rode NT-1 is good but felt too dull, but might come to life with post-processing.

The 24-bit Samson G-Track Pro did not have the sound samples.

Disclaimer: Don't rely too much on random blog posts :)

Update 2019-02-19

I have now listened through a better set of headphones (Sony MDRCD480), and I still believe the above mics are the best in their selection, but I am less sure about the order between them. I also listened to the female soul voice and the AT-2020 does the best job there.

Some between €150 and €200 that sound fine

Audio-Technica AT 2035 €154

the t.bone SCT 800 – Thomann UK €175 sounds nice

Idea: An Android audio recorder that streams VU data over UDP

Posted by admin |

Let's say you want to use mobile phones to record sound locally, but you want to be sure that they are all recording. One way could be to have an app that streams volume data to a server on the Internet. In that way you could have a web page that gives you an overview of all devices recording.

TIL on audio: Small diapraghm mics, Ardour, 24 bit sound & podcastage

Posted by admin |

Small/large diaphragm condenser mics

I've wondered a bit why podcasters are using the old style large membrane mics of yonder. You could see these mics in '80s music videos when they wanted to be retro, such as Robert Palmer's "Johhny and Mary" and Ultravox "The Voice".

The Neumann mic company has a page on this: What Is the Difference Between Large and Small Diaphragm Microphones?

It turns out that strictly speaking small diaphragm mics are better, objectively seen (or, uhmm, objectively heard…). But many people like the sound characteristics of large diaphragm mics. I actually like my very cheap T.bone headset mic ,which is from the cheapest T.bone wireless system. Maybe I'm a small diaphragm mic man.


Bandrew Scott's Podcastage is a fantastic Youtube channel that tests a lot of podcast gear thoroughly and in good spirits. A gem.

Which mic should you choose?

Podcastage come through with a great guide on his web site: — Bandrew Scott

Plosives and sibilance

Turns out they are different things. Plosives is a powerful puff of air that is mainly a problem for large diaphragm mics with a lot of physical leeway.  Plosives can push those membranes to bottom out and they can take some moments to recover. Plosives are caused by "b" and "p" phonemes.

Plosives should be dealt with at recording time, apparently hard to correct in post production. Plosives are why you can see a screen in front of the big mics.

Sibilants are cause by "s" phonemes and similar. They can be dealt with in post by de-essing, which can be done with a two-pass compressor working in the high frequency band.

24-bit sound good

Podcastage explained this very well 16 bit vs. 24 bit Audio, What Should You Record At? (FAQ Series) - YouTube.

…and it's a no-brainer whan you think about it. You get a lower noise floor, and overall better quality. One thing that I will appreciate is that clipping ought to be a thing of the past. Since I started recording on cassettes on analgue, 0db is fine but in digital it most certainly is not! I have to get that into my brain better. With 24 bit (or -24 dB if you want) you can dial down and be far away from 0dB.


Ardour seems to run on my Pulseaudio Linux machine. I thought it wouldn't. I've slaved away in audacity for no reason! :D

Cheap large diaphragm mics I liked, listening to YouTube vids through a tinny laptop speaker

Posted by admin |

Audio-technica 4047 Oops, this isn't cheap! I started listening to samples at YouTube and thought "Wow this is great for a €70 mic". Turns out it's more like €700.

AKG P120 This is a €70 mic. I like what I hear on Youtube. Not as much as the 4047 above, but…

New insights into audio recording for video, from recent sessions

Posted by admin |

So for the situations I tend to end up in, one-on-one interviews, conversations in front of a white board with 2 or more people and sometimes a group chiming in with opinions. here are some ideas with regards to wired, wireless, digital, number of inputs, where to record and so forth.

Insight number 1 — tracks

A video camera usually only has two sound tracks. If you want more mics than two, you will have to record those on a different recorder, being it a camera, a dedicated recorder or a sound card connected to a computer. This means that you need to do synchronization. Unless you are fancy with SMPTE or something, that will be done by matching audio automatically. If you already need to do that, it does not take much more time to match many tracks algorithmically.

Insight number 2 — synchronization

If you already accept synchronizing multiple sources, you might as well have the recording device on the subject. The exception being that two mics should be wireless and their receivers should be mounted on the main camera to get sound and images in lockstep.

Insight number 3 — lapels don't scale

It's a lot of work to mic people up. Well, not a lot of work but it does not scale to when you have 12 or 50 people. A handheld wireless mic which can be passed around can be a good option in those cases. Also, everyone understands how a normal handheld mic works, so don't go for one where you talk at the side of it or something. You could also use a portable recorder for this with built-in mics. Actually that may be the best option.

Insight number 4 — no digital

No need to go digital. It makes more and more sense in our day and age to go digital from the mic to the recorder, but since most cameras don't have digital sound inputs afaik, you'll have to wait for that for a while. And for your other devices, if one believes this blog post's insights to be true, you'll use portable recorders on the person, which come to think of it is kind of all digital, just a very short chain.

A possible setup from these insights

  • Two wireless lavalier/lapel mics with the receivers mounted on-camera. You could go with just one and use the other channel for picking up ambient sound for synchronization
  • Any other cameras used, can take up sound from any fixed mics, including boom mics, indeed they should use this to get some synchronization signal.
  • Two people can be be mic'ed up with the wireless mics,
  • any others can be mic'ed up with lavalier mics that go to a recorder directly on the person's body.


Being a bit more concrete

A. One wireless lavalier mic for the main camera,

for example Røde rødelink newscaster/filmmaker (untested by me).

B. More lavalier mics

All other lavalier mics used, would have their own recording device on the person's body. Here you would need to find good but affordable such recorders, or use mobile phones.

  • Sony has an apparently great little mobile recorder under €100, the Sony ICD-UX560, but ideally you'd want to go a bit cheaper than that. Also, it does not come with a clip, but it does have a mic input with bias (3-5V for electret condenser mics).
  • A mobile phone with e.g. the aputure a.lav mic. I have that one and I don't like it, though.

    I suspect some mobile phones apply compression, maybe there is a way to avoid that. Record that note App works well on Android as a recorder in my experience.

There are some novelties in the field, such as the

  • Sennheiser Memory Mic, but I wish it came in black and not white. It's also at ~€200 a bit on the expensive side.
  • Same price range for the Tascam DR-10L Digital Audio Recorder with Lavalier Mic .
  • There is also the Zoom F1-LP, with lavalier mic, roughly the same price.


C. One handheld microphone

One handheld microphone that you can use for non-mic'ed up people to speak through. Here is a recorder that is of interest for this:

  • Tascam DR-10X Plug-On Micro Linear PCM Recorder (XLR). Aroung €100.
  • Here is one that even supplies 48V phantom power: Saramonic SR-VRM1 Plug-On Linear PCM Recorder for XLR Microphones, around €125.
  • You could also use a handheld voice recorder such as the Sony ICD-UX560 (again) as a handheld microphone.
  • Or even use a mobile phone, possibly with a mic sticking out to make it obvious where to talk. Make sure to have a good screen lock, but not so good that you can't unlock it because the finger print holder went to lunch.

Risks with this approach

  • Uneven sound quality with so many different recording devices.
  • Synchronization not working due to sound images being too different between different mics.
  • It's hard to know with confidence if a local device is indeed recording. With a central mixing desk you could check. Maybe if you use phones you could have them report over the Internet their recording status.
  • People wandering away with the devices.
    If a person wanders away with a wireless mic, you lose the mic. If he wanders away with a recorder however, you also lose the recording from that person! And you will have to edit them out of the video. A fitting punishment maybe :).

Go full insight— No wireless mics?

Actually for when only two subjects need to be recorded, two wireless camera mounted systems might be the best choice. Maybe one should never go go full insight, but you could probably get away with only portable recorders on the subjects, and sync up via the cameras' built-in mics. Actually for when only two subjects need to be recorded, two wireless camera mounted systems might be the best. But, you could probably get away with only portable recorders on the subjects, and sync up via the cameras' built-in mics.
