The important role of good audio in any film is often overlooked. Many consumers don’t purchase an external microphone with their camcorder but instead rely primarily on an internal omni directional microphone which indiscriminately picks up and records sounds from the front, sides, and rear. This often results in a significant amount of “noise” and difficulty in discerning the voices or other sounds which home movies try to capture.

Without making a life study of film making, there are a few quick and simple things the average home movie maker can do to vastly improve the audio quality of films they record with their camcorder.

1. Move in closer to the subject or sounds which the film should capture.

This can mean using the zoom function less and instead, stepping nearer. When recording children, this can also mean getting down closer to their level from a vertical perspective. Getting closer with the camcorder not only allows the film maker to capture the sounds better but it helps to cut down on the amount of noise that will intrude from the background.

2. Home movies should be filmed in a quiet location when possible.

Controlling the environment is an obvious way of cutting down on the “noise” intrusion. Some environments in which we film may be naturally “noisy”; but assuring that the television is off, the dishwasher is not running, etc. certainly helps.

3. Engage the “wind screen” feature on the camcorder when filming outdoors.

The “wind screen” feature does exactly what its name implies; it helps to reduce wind noise. This is particularly useful at the beach.

4. Reduce noise by steadying the camera.

Jarring the camcorder around and moving about while filming can also create a great deal of noise. Using a tripod or another type of stabilization device can not only steady the picture but reduce noise.

5. Purchase an external microphone for your camcorder.

If your camcorder has a jack for an external microphone, this can be a great way of significantly improving the sound quality of your recordings. There are a variety of types of microphones available and each functions best in different situations. “Shotgun” microphones help to reduce noise by cutting out sounds from the side and rear of the camera and recording sounds primarily in front of the camera at a distance. For recording speakers/presenters, a lavaliere microphone is the best idea while Cardioid microphones record sound near, but directly in front of the microphone.

6. Reduce film maker noise.

This is common sense but the person with the camcorder in hand should remember to be quiet and avoid “fiddling” with the controls on the camcorder while filming.

Although none of these techniques are high tech, adhering to them can greatly enhance the quality of any home movie creation and allow owners to better enjoy their investment in a new camcorder.

In fact, with the best of the wireless microphones today such as Sennheiser microphones, you would never be able to figure out whether you are using a cordless microphone or wired one unless you know it already or explicitly see and find out. This is because of the fact that the qualities have become comparable today. The inbuilt laser technology and the capability to reach UHF frequency strengths have made the wired and wireless devices comparable in terms of quality and performance.

However, the Sennheiser wireless microphones add another dimension to the equation. These microphones are great in terms of looks. They have a back light with a lovely glow. The whole base system is put inside a nice-looking case. And of course, the lack of wires makes it even more sleek and elegant. So the users of Sennheiser microphones tend to report enhanced décor which in turn leads to improved mental peace.

And again, Sennheiser cordless microphones have inbuilt noise filtering capability. This means that the microphone will have an inherent ability to smartly figure out which are the real sounds that need to be transmitted and which are the ones that need to be eliminated. Based upon this, the unwanted sound is filtered out and the desired sound is retained.

As you see, using a Sennheiser wireless microphone not only improves the sound quality and adds mobility to your life, but it also enhances your home decor so that you add an asset both in terms of looks and benefits rather than a liability in any department.

There are many different brands of wireless headset mic that range from really cheap to really expensive. The question is, how do you know you’re getting your money’s worth? Find out what separates the losers from top models like the Sennheiser wireless microphone.

A transmitter is used here

In order to get a wireless microphone to work a proper type of transmitter is going to be needed. The transmitter is the main source that the microphone can work with. It features the antennae that are needed to get the microphone to read to the device so sounds can be relayed back to speakers. The speakers that can be used will be either wired to the transmitter or wireless depending on the type of transmitter that is being used. Either way the transmitter will be able to read signals that are in an activated microphone that is linked to it. This is provided that the user is in a close proximity to the transmitter.

Diversity is the key to a wireless microphone

One notable part of this type of entertainment device is the diversity used by the transmitter. This is where more than one antenna is going to be used on the transmitter. This is useful for any wireless microphone because it can work to handle the microphone in many paths and to ensure that dropouts can be avoided. These dropouts, which occur when the signals to a microphone are lost, can be very bothersome.

Safer to use in performance areas

One of the best parts of a wireless microphone comes from how it is something that is safer to use. This comes from the lack of wires involved. There is no need to worry about anyone tripping on wires or anything getting tangled up in wires. There is no need to be concerned about cables causing transmitters to be moved around either.

But when using a camcorder to capture the event under scrutiny, whether it’s a wedding, a speech or presentation or some other significant event, the issue of having the best quality sound presents unique challenges. So its best to do some concentrated planning on how you are going to accommodate the sound needs of the event to your equipment because if you have wonderful pictures but the words and sounds of the event are muddy or lost, then the quality of your final product is seriously damaged.

Many an unsatisfactory video was taken with a camcorder because the operator depended too heavily on the small microphone that is built into the casing of the machine. The only situation where this microphone may be adequate would be if you were conducting a one on one interview in a small room where you could position the camcorder within three feet of the subject. Even then, surface noise from the surrounding building could become part of the audio outside of the awareness of the operator at the time.

To assure that you have complete awareness of what is going onto your video recording of each event, the investment in a good set of closed back headphones to monitor the audio is an outstanding move. You can plug it into the camcorder and you are dynamically aware of what is going onto that tape at all times. If something gets into the audio that is not appropriate, you can use editing techniques or even re-shoot the segment if that is possible in the context of the event.

For the majority of events, plan to use the auxiliary audio input plug to incorporate a mobile microphone unit rather than depend on the onboard microphone in the camcorder casing. This small plug alone opens up a large range of solutions to the problem of poor camcorder audio that is so often endemic of videos made with this technology.

If you are working with an external microphone, be aware of the limitations of the wire if you are not working with a radio frequency microphone unit. In a situation such as a speaker doing a presentation, you can lay the cord down between the recorder and the speaker’s stand assuming you have sufficient cord length to reach the where the microphone will mount on the stand. Be careful with the excess cord, perhaps securing it with duct tape so those listening to the presentation don’t trip on the cord or pull it free which could cause injury and damage the equipment.

In many situations such as one in which you plan to interview people in a roving fashion or to record a speaker who is on the move a great deal, a radio frequency microphone may be necessary. These can be more expensive but without the investment in this technology, your audio quality relying exclusively on the camcorder built in microphone will almost certainly be disappointing.

In all seriousness, there are many positives to this type of microphone beyond the basic, obvious functions it is intended to perform. Understanding some of these benefits may help guide those “on the bubble” about making a purchase to select a Sennheiser wireless microphone lavaliere.

The main benefit to this type of Sennheiser wireless microphone is that it is omni directional. That means it can draw in sound from a fairly decent radius. The most annoying disaster scenario that can develop when making an audio recording would be the person wearing the microphone is not recorded properly. This could be because the microphone slips or it ends up being too far from the speaker’s mouth. Generally, such problems should be overcome by a high quality design with the microphone. Those that employ a cheap, less than high quality lavaliere microphone will discover they made a major mistake. The lack of omni directional recording power ends up delivering low volume sound or poor recordings with dips, peaks, and valleys. A high quality clip-on microphone such as a Sennheiser wireless microphone can often avoid such common problems.

Of course, the audio engineer also has to do his/her part to prevent such problems from developing. The microphone will send the wireless signal to a soundboard. Close examination of the modules on the soundboard will reveal the aforementioned peaks, valleys, and sound levels. Adjusting the dials will correct the problems in the most effective manner.

What happens if the adjustments are not yielding any results? You may have to examine where the Sennheise wireless microphone is placed on the person being recorded. If the lavaliere is too far from the person’s mouth then you would need to adjust it or move it closer. If you are concerned about the microphone being visible on camera in a video recording, you could always tuck the microphone under a collar or even insider of a shirt. The microphone will be strong enough to pick up the sounds it is intended to record.

On the other side of the coin, a Sennheiser wireless microphone lavaliere is also designed to avoid picking up sounds it is not supposed to record. Background noise and other natural sound will not be captured and transmitted with these quality microphones. Those that opt to “go cheap” on lesser quality microphones will discover that there is no benefit to saving money on the microphone and then ending up with jumbled, indecipherable, mixed up sounds on the recording. A Sennheiser wireless microphone will not do this. It is too high of a quality microphone to yield such problems. That is why it is so recommended!

Performers, especially dynamic ones, can do away with entangling cables that may even cause them to trip. They can move about the stage without worrying about not being heard. The wireless microphone is actually a technical misnomer because it still uses wires. The “wireless” in the term actually refers to the cable which connects the device to the amplifier. Various technologies are used to establish this transmission without the standard cable. Some of these devices use infrared light much similar to the technology used in remote controls. The most common ones use radio waves transmitted thru UHF, VHF, Fm, Am, and many other modulation frequencies.

One of the advantages of a wireless microphone is, as we have mentioned, the freedom of movement it affords the performer or speaker. You can do also away with the most common problem of cabling (especially for dated cables) which is the internal wires breaking their connection once in a while causing the sound to come out intermittently.

The disadvantage of these wireless gizmos is that their ranges are limited to a radius of 300 ft (100 m), although the high-end models can beat this range easily. Interference from and with other radio equipment or other wireless microphones cannot be avoided although the latest models come with synthesized frequencies that can be switched to other channels.

They have a limited operation time because they rely on batteries for their power supply. There are some areas wherein noise is generated while in some areas there are dead spots. The number of units functioning at the same area at the same time is limited to the number of radio channels the devices are capable of.

The wireless system is composed of an input gadget, a radio transmitter, & a receiver. The input gadget, which is a microphone, supplies the audio signal. The signal is then sent by the transmitter and received by the receiver.

These microphones can be grouped into handheld and body pack. The handheld units are much like the regular microphone except that instead of a cable it has a battery pack & a transmitter. The body pack microphone is composed of a box as small as a deck of cards. It is clipped on close to the user’s body. It can either be connected to a headset mike, a lapel mike, or to an instrument such as a guitar.

Now, while there are some fine desktop microphones on the market, I don’t recommend any of them for audio or video production. Why?

Because they can be moved to different positions on the desktop and that means that each time you record you have to adjust it to ensure it is positioned in exactly the same position as your last recording or the recording volume won’t be consistent. This is especially critical when you’re doing long recordings, take a break, and come back to continue recording.

The second undesirable feature of a desktop microphone is that, even if the microphone remains in exactly the same position, you as the user don’t. You don’t sit perfectly still when you’re using the computer. You’ll turn your head, scratch, or whatever, and your head and mouth placement will cause your recording levels to fluctuate.

In fact, in order to ensure consistent sound recordings with a desktop microphone, you almost have to lean into the microphone – just like you see radio talk show hosts doing. The reason they lean into the mic is to make sure that the sound quality and volume remain consistent. And this, obviously, presents a difficult challenge – especially when you’re working on the computer a the same time. Again, recording volume consistency is a must in professional audio and video recording. So save yourself the hassle skip the desktop microphone option.

Next is the lavalier microphone. This is the type of microphone used by the NBC news anchor I keep saying I’m going to make you sound like. But, guess what, I don’t recommend this type of microphone for extended audio and video production work.
