2/11/2014 7:11:25Sample rate I think would be the hertz of the recording you are picking up.. So the higher it is the better/clearer the recording is.The higher the sample rate the higher the frequency spectrum (it is picking up more noise that a lower sample rate would not record/pick up)You would want a higher sample rate over a lower sample rate to achieve a better recording. For example if you are recording omni-directionally you would want a higher sample rate to be able to hear the noise from all around the room that it is picking up better.Auto vs manual gain control would be do you use the auto selected settings for recording chosen by the manufacturer (the base settings it comes with) or manually pick the file type, how far its picking up, how it reacts to loud sounds ects...mp3 is the more compressed file format (and the most widely used)...
wav file
Mono recording is just from one mic (for example the left one)
stereo is both
if youre recording from just mono and not inputting it into both channels you would only hear it from one side..
I have no idea.I have no idea.

2/11/2014 7:18:01a sample rate has to due with the amount of samples taken from a wavelength.
frequency spectrum involves measurement which has alot to do with depicting which sample rates are more effective or stronger depending on environment or what is actually being recorded . in my opinion a frequency spectrum is a sound graph.a higher sample rate which can be measured at a better frequency (hertz).
limiters- specific ranges
auto- settings are already set to its appropriate range .
manual - you choose the settings.
low cut filters - cut out frequencies on the low end .
mono deals with one channel. wav records under two channels.mono deals with one channel. not surenot sure

2/11/2014 7:21:05Sample rates are files which are based on Hz. For example a piece of recording with a bit rate of 34 Hz.Sample rate is strictly for quality purposes. While frequency spectrum is based on the integrity and intensity of a recording.For better quality and you would wanna record on a sample rate of 26 Hz then 20 Hz.Auto is sets a record time and end time. This is suitable for solo recordings. Manual requires timing, and this may be suitable for a multi recording media. Limiters are much shorter and are multi as well. Compressors single out a multitude of sound into one piece. Finally, low cut filters are kept short and are for multi recordings.MS recording and XY recording. MS mode is mid range recording mode. While XY has a much wider range.A mono recording is a 2ch, while a stereo recording is 4ch. Mono is hearing on one side while stereo is both (surround sound). You hear a mono recording in one ear because of the type of channel the recording is on.A microphones polar pattern goes inward according to XY. That the microphones function is flexible in many ways.A dynamic microphone is a cardiod type of microphone. A condenser microphone compresses incoming sound.

the higher the sample rate the biger frequency spectrum you can haveyou get a more accurate sound, you are taking more of the original wave length auto- chooses settings for you
manual- you choose settings
limiter- will only pick up specific range of frequencies
low cut filters- cuts out the low end frequencies
mp3- compressed file
wav- uncompressed file
mono- one channel recording
stereo- recording using 2 channels

2/11/2014 7:25:07An example of a sample rate is 44.1khz. Not sure but a sample rate is probably the amount of sound frequency that can be handled.The relationship between sample rate and frequency spectrum is that the higher sample rate the more the frequency spectrum is expressed. For example if the sample rate is high then it covers more of the frequency spectrum instead of cutting off highs and lows along the spectrum.You would choose to record at a higher sample rate so that you can pick up high pitch sounds. A lower sample rate would only be needed for lower pitch sounds. If you had to record a violin you would use a higher sample rate so that it can pick up the higher tones with more quality. You would use a lower sample rate for deep low sounds such as a drum or a regular human voice.auto affects the gain because it's going to adjust the gain control based on the input that it receives. Manual affects the gain control because you can set the gain control yourself using the manual gain. Auto simply automatically sets the gain control and manual is set by what you want it to be. Limiters are the certain aspects as to which the recorder can record. It could have a limiter for a concert performance and that would affect the gain because it would change the level of gain control. Compressors compress the recordings and may leave out some highs and lows. Low cut filters set the minimum amount of dB's for recordings. Both compressors and low cut filters affect the gain control because of what levels they are made for such as certain highs and lows.Wav and mp3 are the two formats. I believe the difference is simple one is more compressed than the other.Recording channels are what receives the sounds that your recording. They can be four channels which would allow surround recording. Mono means there's only one channel while stereo means there's two channels. You would only hear a mono recording in one ear because the play back would only play on one speaker not two.Not sure but maybe a microphone's polar pattern is the pattern in which the microphone can receive sound. This gives the microphone a certain purpose for use. Like a shotgun microphone is only used for directional recording. Not sure.

2/11/2014 7:25:25Sample rates is the amount of samples taken from a wavelength. Some examples of sample rate is 44.1 KHz and 48 KHz.The relationship between the two is that sample rate is measure in hertz which coincides with frequencies. I would choose to record at a higher sample rate if I was recording a high frequency. An example of this would be someone talking at a high pitch or symbols.Auto gain is when the recorder controls the gain of a recording for you. Manual gain is when you have control over the gain of the recording. Limiters control how much of a certain frequency is allowed to be recorded which affects what can be heard in the recording. Compressors will tend to cut out a portion of the recording, this will cause the recording to sound like it is missing certain sounds.The two file formats are WAV and MP3. The difference is that WAV is uncompressed while MP3 is compressed.The channels of a recording are mono and stereo. Mono records in one channel while stereo records in two. You would only hear a mono recording in one ear because it is only on one channel.A microphone's polar pattern is the direction in which it records. This tells that the microphone needs to be in a certain direction to record. Some examples are omni, cardiod, and uni. A condenser microphone will pick up better on someone talking than a dynamic microphone.

2/11/2014 7:26:34sample rate is the amount of sample per amount of time.One example of a sample rate is 44.1kHzThe relationship between sample rate and the frequency spectrum is that both measure using time.
I would choose to record at a higher sample rate over a lower one because the higher sample rate I think picks up a more higher frequency so it's easier to hear.auto gain controls the amount of sound from the recorder. manual is whatever you set your recorder to. Two recording file formats will be mp3 and WAV. WAV is standard for audio bitstreams and mp3 is a compression of sound sequences into one file.The channels of a recording is mono and stereo. Mono is a recording from one direction, which is why you hear the mono recording in just one ear, and stereo is recorded from all different directions. A microphone's polar pattern is the mic's directionality. For example cardioid.dynamic microphones have an electromagnetic induction and a condenser has a capacitance change.

2/11/2014 7:28:16some examples of sample rates are the relationship between a sample rate and a frequency spectrum is that they both have diff levels that they go up to.
The reason most people choose to record at s higher rate is because the sounds sound more clearer and louder.Low cut filters allows the listener and recorder to have the information at a more clearer level.Two file formats that are different and record at different rates are audio file format which stores digital audio data on the computer and PMC which stores the uncompressed version of the audio on the computer such as MAC. The difference between mono and stereo is the simple fact the with stereo recording the sounds that are being recorded at recorded at a much higher rate.The polar pattern varies as the noise level increases.A dynamic microphone is able to pick up the sounds at a more clearer rate that a condenser microphone would.

2/11/2014 10:28:19Sample rates are the how many sounds the device can detect at once. The higher the sample rate, the better the sound quality. An example of sample rate is 192 kbps.Sample rate and frequency spectrum are related in the way sound is recorded. The higher the sample rate, the more it is capturing the frequency spectrum. You would chose to record at a higher sample rate if what you are recording has multiple sound sources. For example if you were at a park trying to capture as much of the natural sound as possible, a higher sample rate may have the ability to capture the wind, the birds chirping, trees rustling and so on as opposed to half of those things.Auto vs. manual means that the gain (the volume at which it records) of the recording is controlled by the user or recorded at a preset level. Limiters allow for the gain to go only so far in volume (measured in dB's). Compressors compress the sound for smaller sound files. Low cut filters get rid of the low end of the recordings.Two recording formats are WAV files and MP3 files. WAV's are uncompressed and MP3's are compressed.Channels of a recording are how many sources it's recording from. Mono is recording from a single source whereas stereo is from two sources. Mono recording will some times be heard in only one ear because it would be the same audio in the other ear. Why would you need to hear it in both? A microphone's polar pattern affects sound quality. A microphone turns sound into electricity and amplifies it at a higher volume.A dynamic microphone records anything and everything in its area whereas a condenser microphone will only hear what the user allows it to.

2/11/2014 10:29:22sample rates are the rates on of the sound that one records on their input.it is the number of sample per unit of time. the number of audio carried per second. Frequency spectrum is the sound recorded and the level it is recorded at. any function that varies with time. So while for sample rate we look at the sound recorded for every second, In the frequency spectrum we are able to see the levels of sound through a period of time. If you are in an enclosed environment and the individual or object you are recoding is singular, you may only need to use a lower sample rate. If the setting is larger and the sound intake is bigger you should need to use a bigger one. auto is what we usually set our devices on. compressors are found in the file formats. low cut filters are used to distinguish a certain sound from another.wav and mp3
wav is compressed.
mp3 is not compressed.
mono recording is a focused recording, and it is on one channel. therefore you can hear it on one ear. stereo is the left and the right ear, which holds two channels. a microphones polar pattern is the shape of the microphone and the sound it can take in with its individual shape.The area around the microphone.dynamic is the microphone we used for recording on larger settings. And a condenser microphone is probably what we use for human speakers. The dynamic microphone is what is used during a karaoke session, for immature singers. And a condenser mic is often used for recording artists in studio. The condenser microphone is able to filter the sounds of the voice, and give a echoing effect.

2/11/2014 10:29:3644.1kHz, 48kHz, 198kHzThe frequency spectrum is the wave vibrations of the audio that is being recorded. The chosen sample rate depends on how good the audio recorded is as close to resembling the original audio that was recorded. So a smaller sample rate the the smaller the quality of the recording, and the higher the sample rate the higher the quality of the recording and the minimum cuts on estimation it recieves.A higher sample rate records/ re-creates at a closer wave frequency than a lower one does. So the higher the sample rate the less audio per frequency is cut and the better the quality.Manual affects gain, where you have control over the level of audio coming inmp3 - this is a compressed audio format and it cuts out some quality of the audio and is usually a smaller format.

wav - this is a better format than mp3 gives better quality and are usually bigger files than mp3.
The channels of a recording can be stereo or Left mono, Right mono or dual mono(meaning both). Mono gives you one channel of audio. So Left mono would be the left channel alone and the Right mono vice versa. Dual simply brings both these channels to be recorded together. Stereo is multiple channels being recorded or played together. You would hear a mono in one ear because it is more direct.A microphone with an omni polar pattern gives a globular pattern and this tells us that it is capable of detecting audio all around in range and it doesn't need to be directly on front of the microphone. A microphone with a cardiod polar pattern, is usually gives a smaller and more oval shape pattern. This tells us that this is microphone will only detect audio within range in its direction.A dynamic microphone such as a shotgun, or a Shure SM58 is limited in sound and detects only the audio directly in range, these are studier and reproduce the audio through coil vibrations and don't usually need to be powered. Condenser microphones the small lavliers or the built in mics in the recorders are designed to detect more in the omni pattern.

2/11/2014 10:29:48Sample rates are the rate in which your audio recording takes sample from a continuous signal.I believe they are basically the same except frequency is measured in Hz.I believe you would choose to record at a higher sample rate because you will be able to use a higher frequency. auto vs manual is quite self explanatory. Auto does it automatically, manual helps you control it. Limiters help allow audio signals to record even with a lower input power. Compressors help reduce the volume of loud sounds. WAV and MP3.. WAV: Is the Uncompressed of the audio file
MP3: Is a compressed version of the audio file
Mono and Stereo. I believe the difference between mono and stereo is that Mono allows you to record through one input (such as the left or right ear) and stereo allows you to record through all inputs. I think Mono stands for one, so that's my only explanation for audio recordings being recorded in one ear in mono.A microphones polar pattern is how sensitive it is when picking up audio. It also has to do with the sensitivity to the angle in which the microphone is pointed towards. For example an omnidirectional mic can record equivalent volume levels at all angles of the mic while a cardioid mic is more sensitive when recording anything in front of it.Dynamic and Condenser microphones differ from the way they use power to record sound. For example a condenser mic uses an electrical power to record sound while a dynamic mic doesn't.

2/11/2014 10:29:54unit of time taken from a continuos signal, to make a discrete signal.sample rate and frequency spectrum are both dealing with a continuous signal.you should record at a higher sample rate because you won't lose as much sound. when the sample rate is low there will be big gaps causing lost of sound.?MP3 and WAV.-stereo and mono.
-Mono you hear through signals that are mixed together and sent through a single auto channel. Stereo are signals that are recorded separately and are sent through two separate channels.
Microphones has a small metal piece inside that vibrates when waves are being pushed through it allowing for sound to be produced.a dynamic microphone has no internal amplifier and do not use battery or external power. condenser microphones on the other hand has something in it that allows low ends to be cut and are operated by external power.

e.g. of a dynamic mic is the RE11

2/11/2014 10:38:13Sample rates are the frequency's taken from analog recording converted into other digital mediums such as wav or mp3.Sample rates take data from frequency's. Thus a higher frequency and significantly lower sample rate can result in poor sound quality and vice-versa. Because you wouldn't want to get aspects of the recording lost in the translation of analog to digital. Many avid music listeners would proclaim this is a key issue of itunes vs vinyl. Auto vs Manual determines how your gain (volume level of your recording that's going in to the device) is actually recorded. Compressors and limitersn/an/an/an/a
