    How to Make Your Own DIY U87 Vintage Condenser Mic
    https://www.youtube.com/watch?v=DtNH46jpwJo

    Neumann’s “holy grail” of workhorse condenser mics is now closer within reach than ever before, thanks to a capsule and body from http:///www.microphone-parts.com and circuit boards from Dany Bouchard (http://vintagemicrophonepcbkit.com).

    DIYer Matthew Jenkins walks us through his build, employing parts from Cinemag (cinemag.biz) and Mouser.

    Probably the best phone mic ever created, sounded really good, Shure has sure outdone themselves.

    good video. i bought one but returned it since it won’t work with any
    iphone or ipad in a case. although the sound was pretty good, I get much
    better recordings out of my tascam digital handheld. in the end, it all
    depends on what you want to do with it. I also found this mic to me a
    little hollow-sounding and not too real or full. i’m picky. been into
    film and audio engineering for years. great channel you have!

    DIY Microphone Amplifier for Shotgun Microphones
    https://www.youtube.com/watch?v=q9Q_XnvTxa4

    One of the biggest problem that i encountered during video production is bad audio. Audio makes 50% of the video. When a video have a bad audio, even with a greath content, it is very difficult to watch. I have a shotgun mic that works pretty well except for the signal intensity. It is pretty weak and my camera doesn’t offer a good audio preamplifier. So i decided to make my own, external and directly connected to the microphone. The idea is to get a 20dB boost, with a variable volume, sharing the same battery and controlling everything with just one switch.

    https://www.thomann.de/fi/onlineexpert_page_large_diaphragm_microphones_large_and_small_diaphragms.html

    Diaphragm size plays an important part in directivity. Large diaphragm mics become more directional at higher frequencies. This means that on-axis sources appear brighter than sound coming from the sides (off-axis). Also, impulse response on large diaphragm mics is not quite as excellent as on small diaphragm mics, because the diaphragm mass is slightly heavier. But that’s just a generalisation. Impulse response on LD condensers is still more than sufficient.

    Large diaphragm mics, however, do have one advantage over small diaphragm mics that’s relevant in many recording situations: Large diaphragm mics have a better signal-to-noise ratio. A larger diaphragm produces a stronger signal while the amplifier noise remains the same. A louder signal above the same noise floor means better signal-to-noise ratio.

    Bottom line: small diaphragm mics perform better than large diaphragm mics in many disciplines, but large diaphragm mics have one advantage – low noise – that outweighs other factors in many situations.

    Altoids USB Condenser Microphone
    https://www.instructables.com/id/USB-Microphone/

    Record quality audio at home with a Homebrew USB Condenser Mic! This week, we are hacking a tiny little gadget, the USB soundcard, and turn into a studio quality microphone. It’s a microphone that carries the whole package, it has a shock-mount, pop filter, preamp and an internal DAC.

    The project was housed on a Retro Altoids container. Its cardioid pickup pattern, smooth frequency response and 16-bit, 44.1/48kHz resolution give you professional audio results no matter what you’re recording.

    Why Make a USB microphone?
    USB microphones are made for easy, plug-and-play use. They’re fantastic for podcasters, musicians, voice actors, audio students, tech-reviewers and people who just want something better than the microphone built into their laptop. If you don’t have a USB mic, you might want to try a Homebrew version before you buy one! Don’t worry, the project fits on a $10 budget! DIY is the most rewarding thing to do!

    Can I parallel microphones into one input of my mixer?
    http://www.shure.com/americas/support/find-an-answer/can-i-parallel-microphones-into-one-input-of-my-mixer

    Wiring Microphones in Parallel

    Connecting microphones in parallel allows more than one microphone to be connected to the same microphone input of a mixer. This reduces the cost and complexity of the sound system, since fewer mixers and microphone-to-mixer cables are required. There are tradeoffs, however

    It is not possible to adjust the level of one individual microphone.
    Only dynamic microphones may be used.
    In Push-to-Talk applications, the switches on the microphones must be of the Normally Open type
    If two or more mics are activated at the same time, the output level of each mic will be less than if only one mic is activated.

    THE CHEAPEST MIC IN THE WORLD!?!?

    This video tests 22 dollars microphone BM-800

    Comments:

    It seems that there isn‘t really awful stuff on the market nowadays, you just have to figure out how to use it and get the best results possible

    I listened to this on my studio monitors – as I do with most of your videos. I also have subs connected. The most glaring difference I noticed is the cheap mics roll off bottom end. The U47s have a much wider dynamic range. So I would say if you’re recording low end, give these a skip… Otherwise generally I thought they sounded alright. You can’t beat the price!

    How The Microphone Changed The Way We Sing – Cheddar Explains

    Ever wonder why some old songs sound outdated and others sound like timeless classics? Cheddar explains how the invention of the microphone changed the way vocalists sang love songs.

    From video comments:

    Josh Turner Guitar

    Excellent and very engaging video. A few notes, for what it’s worth:
    Early, pre-microphone recordings were done on wax cylinders, which predated the disk shaped record.
    On Frank’s mic technique: part of what made it so great was his use of proximity and axis not only for the control of sibilance and plosives, but also minute control of volume, allowing him to bellow one phrase and whisper the next with equal intelligibility. He also used proximity effect to his advantage, the tendency of microphones to build up low frequencies when a sound source is closer, which gave his voice a warmer quality in those whisper like passages. AND, finally, it might be worth mentioning the next huge leap forward in technology – the Neumann U47 condenser mic with which frank is pictured many times here. It is vastly more sensitive and has a wider frequency response then all of its ribbon contemporaries, and would have allowed him to tailor his performances that much more. (Although, as a side note, “Always” would still have been recorded on a ribbon). Hope this is interesting/helpful!

    at2020 is litle bit better to talk, but bm 800 get a better sound on singing

    definitely not! the bm 800 might sound better dry but thats just the microphone slightly distorting due to noise. imagine trying to do louder forms of singing into it, would be a nightmare. you can get the exact same effect on the at2020 with some distortion or a tube saturator and it’ll actually be a better and more pleasant distortion.

    Comments:

    This mic does require 48 volts phantom power. If you do some simple research, you will find out what the circuit board actually does. It will not blow up using a 48 volt phantom power supply. It will actually work at optimal performance.

    It is nothing but simple small condensor mic of rupees 10 in india. With small amplifier circuit.

    Great video Joeteck. Now I’m wondering if ALL the mics like this one (and there are a lot on the market that look exactly the same) are built the exact same way?

    I no longer use this because the quality is just not there. Overdrives like mad, regardless of the mixer settings.

    I bet they are all made in same factory w/different names it’s obvious they are the same mics.

    Microphone electronics theory tutorial for project and home recording studio owners

    Comments:

    Even if your ribbon mic has a low output, you may get sufficient level into a mic pre, which doesn’t have a ribbon mode, simply by close mic’ing, or when you are recording a loud source (eg guitar cab). If the noise level is acceptable and you like the sound, use it. We’re not familiar with the Cloudlifter but because the low level at the mic pre is due to impedance problems, you would need to be sure that the Cloudlifter is addressing this issue and not just amplifying the signal from the ribbon. Although many ribbon mic’s don’t need phantom power, and some may be damaged by it if it is engaged when the the mic is connected/unconnected, it is recommended to check and take care. However, many new ribbon mic’s have active electronics which require power and protect the motor from damage.

    BM-800 Microphone Review – BM-800 With and Without Phantom Power Test – Budget Buys Ep. 21

    Today I take a look at one of the most common beginner microphones on the market, the BM-800.

    Once again, I break out the audio spectrum analyzer to test the quality of this mic, and this time I actually test it in two different configurations. The BM-800 can be used both with and without phantom power, and the difference between the two setups are like night and day. Also, keep in mind that I have done no post processing other than volume adjustments where necessary, so this video should give you a really good idea of the quality you can expect out of the BM-800.

    Comments:

    you are still using phantom power to power the microphone. the 4v the soundcard gives off is enough to power the bm800. it is impossible to use a condenser microphone without phantom power.

    Yes it does work even only with a soundcard but it will not give you the maximum capability of the condenser microphone. Try replacing your USB soundcard with any audio interface if you want to use your microphone to its maximum capability

    What Is the Difference Between Electret Condenser and “True Condenser” Microphones?
    https://www.neumann.com/homestudio/en/what-is-the-difference-between-electret-condenser-and-true-condenser-microphones

    Studio microphones are often advertised as “true condensers”. What does that mean, and is there such a thing as “false” condenser microphones?

    There are two ways to apply this electric charge. The traditional way is to polarize the capsule with an external voltage. In studio applications, that’s no problem. The standard powering system is P48 Phantom power, which delivers 48 volts – enough to polarize the capsule, although many modern condenser mics contain voltage converters for even higher voltages (usually 60-80 volts).

    Another polarization method is to “freeze” an electric charge permanently in the capsule. This is done by applying a special substance called “electret”.

    Good sound is not simply the result of a particular polarization scheme. Superior sound quality comes with great engineering and high attention to detail in manufacture.

    Over the past few years a general nostalgia for the 1980s has infiltrated music, film, and television. I deeply love those gated reverb drums of the ’80s – you know that punchy percussive sound popularized by Phil Collins and Prince? So for my second episode of Vox Pop’s Earworm I spoke with two Berklee College of Music professors, Susan Rogers and Prince Charles Alexander, to figure out just how that sound came to be, what makes it so damn punchy, and why it’s back.
