What are the audio formats? including less commonly used , what does kbps mean in an audio file?

Kbps kilobits per second, also known as kilobit rate, refers to the transmission rate of digital signals, that is, how many kilobits of information are transmitted per megalocaust second (k represents thousands, and kb represents how many kilobits are transmitted).

kbps can also represent the transmission speed of the network, in order to visually appear that the transmission speed of the network is fast, most companies use kb (thousands) to represent it. If it is a kbps with an uppercase b, it indicates how many kilobytes are transmitted per second. 1kbyte s=8kbit s (generally abbreviated as 1kb s=8kb s).

khz: is the sampling frequency.

khz, kilohertz, is the frequency, which can also be said to be the sampling rate.

Generally yes, because that's the standard for stuffy **cd. At present, the commonly used sampling frequency of sound cards is generally 1,000 sound samples collected per second) 11kHz, 22kHz, and the sound obtained by the sampling rate is called ** sound quality, which basically allows you to distinguish the voice of the caller; 22kHz is called radio sound quality; This is called CD sound quality. The higher the sampling frequency, the better the quality of the sound file obtained, and the larger the space occupied by the magnetic (optical) disk.

A CD-quality song will take up about 45m of disk space.

kbps: bitrate is delayed.

It is the number of bits of data transmitted per unit time during data transmission, and generally the unit we use is kbps, that is, thousands per second.

KB (kilobit).

per) second (seconds).

Multiply the kbps data by the song time to know the song file size.

khz sampling rate.

The general CD standard is the start-up, and there is also the 48kHz standard. As long as it is more than twice the frequency of the analog signal of the sound, it can be lossless, so there is almost no shadow and no false sound on the sound quality.

Kbps bitrate. The bigger the better. This parameter is not required for the FLAC and APE formats, as they are lossless.

It stands to reason that the sound quality of the larger ones should be better, and maybe your 9MB is already very good, so the converted ones can't be compared.

Kbps, also known as bit rate, refers to the transmission rate of digital signals, that is, how many thousands of bits of information are transmitted per second (k represents thousands, kb represents how many thousands of bits); kbps can also represent the transmission speed of the network, in order to visually appear that the transmission speed of the network is faster, the general company uses kb (thousands) to express, if it is kbps, it means how many kilobytes are transmitted per second. 1kbytes s 8kbps (generally abbreviated as 1kbps = 8kbps). ADSL's speed is 512 kbps, and if converted into bytes, it is 512 8 64 kbps (i.e. 64 kilobytes per second).

You're converting the audio format without changing the sound quality.

kbps refers to the number of bits (bit rate) and bit rate refers to the number of bits in a data stream.

The amount of information that can pass through per second. kbps stands for "kilobytes per second", so the higher the value, the more types of data halls, the higher the bit rate, the larger the amount of information, and the better the sound quality, but it also means that the more processing of this information is processed and the more space the file needs to occupy. (However, these are not pretending to be guesses about today's hardware, and a lot of people put ape directly on the hard drive!)

For ***, 128kbps is considered a qualified quality! As for what kind of bit rate you use, it depends on your own needs, if the requirements are high, use CBR320kbps, CBR192kbps, or variable bit rate VBR, if the file size is required to facilitate network transmission or ****, use CBR128kbps or lower bit rate!

The higher the number, the better the sound quality.

Bit Rate Description Bit rate refers to the amount of information that can pass through a data stream per second. You may have seen audio files described as "128 kbps ***" or "64 kbps wma". kbps stands for "kilobytes per second", so higher numbers mean more data:

A 128 kbps *** audio file contains twice as much data and takes up twice as much space as a 64 kbps WMA file. (In this case, though, the two files sound the same.) Why?

Some file formats make more efficient use of data than others, and the sound quality of a 64 Kbps WMA file is the same as that of a 128 Kbps ***. The important thing to understand is that the higher the bit rate, the larger the amount of information, the more processing it will be to decode that information, and the more space the file will need to occupy.

Choosing the appropriate bit rate for your project depends on your goals: if you want to put your VCD on a machine, it must be 1150 kbps and the audio must be 224 kbps. A typical 206 MHz Pocket PC supports MPEG** up to 400 Kbps**—beyond which exceptions occur.

For example, a free *** song, it has three versions: 96kbps (96 kilobits per second kbps and bit rate), indicating the amount of data per second, the higher the kbps value, the better the sound quality, the larger the file size, and the longer the time. Users generally agree that the 128kbps *** file is the closest to CD sound quality, so if you like CDs, you should choose the 128kbps version.

The sampling frequency refers to how many times per second the original state front sound is recorded, expressed in Hz or Khz, the higher the sampling frequency, the better the sound quality, but the larger the file size. With sampling accuracy of 8 bits, 16 bits or more, it tells you how much information the computer records for each sample of the original sound. , two-channel, 16-bit sampling accuracy is what we usually call the standard of CD sound quality.

I also learned this part of the content, simply put, the higher the two values, the larger the file, the better the sound quality.

option settings for me to choose.

frequence(hz) drop-down bar from 8000, 11025, 16000....Arrive.

48000。What do these numbers mean?

Addendum: If you don't understand the mistake, it's to let the settings.

Audio settings the "Ratio" of the screen, and select the audio sample rate. The higher the sample rate, the better the sound quality and the larger the amount of data. You can set the sampling rate according to your needs, and the general production of ** will, ** file of music appreciation, should use a sampling frequency of 44100Hz.

To make a general multi-** presentation file, 22050hz is sufficient.

You try it as I said.,I haven't used that software.。。。
