popular sound recording and post-processing software GoldWave tutorial
Top view and download from a well-known, GoldWave is undoubtedly a leader in this area
GoldWave v5.25 Chinese Version (extract directly used without installation)
http://www.crsky.com/soft/1976.html
a set of sound editing, playback, recording, and conversion of audio tools, compact, functional but not weak. Audio files can be opened quite a lot, including WAV, OGG, VOC, IFF, AIF, AFC, AU, SND, MP3, MAT, DWD, SMP, VOX, SDS, AVI, MOV and other audio file formats, you can from a CD or VCD or DVD or other video files to extract the sound. Contains a wealth of audio processing effects, from the general effects such as Doppler, echo, reverb, noise reduction to high-level formula (using the formula in theory can produce any sound you want), the effect a lot.
GoldWave tutorial
Section I: transcription
our so-called transcription, in fact, talk about specific, is to open an existing audio file , and then re-save. Of course, we do not do pure general transcription, the process must include a number of existing audio processing.
However, since the tutorial Well, we put into the back part of that process, take a look at pure “transcription” ~
save the file to open the first of course, is to open a file. Previously, we have seen GoldWave start interface will not repeat it here.
click “Open” button, or “file” – “Open”, select a sound file

after decompression , to reproduce the process, an audio file was opened
We see the main interface, and many would not choose the menu and button has been activated
we open the is a stereo file, so GoldWave will show the two machines defecate annual fee credit card consumers of the new rules a channel waveform, the green part represents the left channel, red for right channel

the main interface, status bar at the bottom of some of the current state of audio files, such as time, frequency, etc.

we click on the right side of the controller in the” Play ” button to start playing
can see the main interface, there will be a translation of the gray line, which represents the current playback position
controller can be seen in concrete wave, and the volume of left and right channels and other information ….

Some people may ask why it has two play button on the controller the other button is what to do with it
Good question, we introduce the characteristics of GoldWare, the first one is the “* intuitive, customizable user interface makes the operation more easy;” < br />
we click on the Properties button on the control panel, or press the shortcut key F11, you can open the controller property
Here, we can adjust the playback properties, recording property, volume, visual properties, and sound equipment
such as the first one, set playback, you can define the button to play all of the waveform, selected portions of the waveform, not selected parts of the waveform displayed in the window part of the waveform, and so on …..
Also, you can adjust the speed of fast forward and rewind.

just said, we do not first consider how to edit, just pure introduce a “transcription” process, so once we skip all the editorial content directly save
Select “File” – ” Save as … “

select the saved file name, path
Note that the following” attributes ” including compression ratio, the sampling frequency, sampling accuracy, the sampling frequency is, in fact, introduced just above the “frequency”
higher the frequency, the larger the file, whereas the lower frequency, the smaller the file < br />

II: acquisition
very simple introduction about the transcription, in fact, just to help you familiarize yourself with GoldWave interface, while learning open and save, and several important characteristics of sound “compression rate / sampling frequency / sampling precision” There is a simple to understand.
Well, we immediately began a further introduction, here is the sound of the “capture”
so-called acquisition, as if a number of professionals, in fact, plainly, what we usually say recording
upper left corner of the main interface, click the “New” to create a new audio file
In the dialog box which we can set some parameters of the new audio files, such as channel, sampling frequency, the length of the audio files and so on.
sampling frequency is usually 44100 on already. If you have a special need, of course, according to their needs change.
length depends on how long they have to record the voice of it, if you are not sure you choose a long point.
After all the settings, click OK.

good a new blank audio file, you can start recording a
Hold down the ctrl key and click on the controller red dot (recording key) began collecting
finished recording a sound, you can edit the selected part, the method is to determine the starting point of the left mouse button, right mouse button to determine the end point ~

due to limitations, we can not have a professional studio that completely quiet environment, but, due to acquisition of equipment is not professional (eg microphone), we will find collection to the audio file very satisfactory results, this time you need to use a number above the “post processing” of the ~
together behind the introduction of specific, here only a basic, “down noise “
We chose the” effect “-” filter “-” Noise Reduction “

For most non-professional friends, we should not so much to study the professional terms, we need to do is just click OK
Of course, if you can depending on the circumstances, to do a write set, of course, good ~

try it again, all without the ambient noise (see the waveform also look out, a lot of neat )
If you are professional enough, you can record a noise to noise reduction as late samples, so the effect will be better
way to open your recording equipment, as keep quiet, 10 seconds is sufficient

III: post-editing
we say in front of the sound recording with GoldWave and open, whether to open an existing audio file or record a new audio file, I usually need to be such a door as the editing and production, the production, collectively referred to as “post-production “….

audio post-production, is actually a very complex process, many parts need some professional basis, in fact, for most of my friends, can be used to, are some simple, basic operations, let say, is the post-production of some simple, basic the operation.
1, the choice of audio files, cut, copy, paste, delete, and cut …..
audio file of choice
with the just introduced, and the left mouse button the specified select Start, right end of the specified selection
shown, select the period of the waveform
we can see in Figure, selected waveform shown in blue background, not the selected waveform display with black background.

select a waveform, this waveform we can deal with a variety of
First Cut , paste and copy ~
and we are familiar WINDOIWS operations, the copy is to retain the current waveform, copied to another new location, and delete the current file will cut the equivalent of “a wave to move the new location “
Note that, paste in here there are three different ways
we can see the button, respectively named” Paste “,” sticky new “and” mixing “
their difference is:
Paste: to copy or cut part of the waveform of the selected insertion point is equal to adding a waveform
sticky new: part of the waveform to copy or cut and paste into a new file, save to a new file is equal to
mix: part of the copied or cut waveform, and the insertion point in the same wave length mixing
and above there is a mix closer to the action, “replace” part of the waveform to copy or cut, replace the insertion point the beginning of the same length of waveform

removed and cut
delete waveform: the waveform directly to delete a selected, rather than remain in the clip board.
cut waveform: waveform and delete similar difference is to delete the segment is to delete the selected waveform, while not cutting the segment is to delete the selected waveform
to describe in simple language, delete can be called the “Delete selected” cut is “Remove unselected”
shown, cut the effect, automatically enlarge the remaining waveform Show

simple operation for over, say roughly what part of the complex operation of it, which is the usual audio capture, processing often use to
1, compressor, expander
For example, we record your own voice, more commonly, in the acquisition process, there are a few excessive force, sound recording came out distortion, while there are a few voices are too small to hear.
this time, we need to use a compressor, expander, popular to say, is the treble “compression down” the bass “expansion up” the intensity of the sound to play a balanced role.
select the “effect” – “compressor, expander”
window as shown below < br />

we need to know two concepts, threshold and increment threshold
: that we need to use the” compressor, expander “to compression and expansion of the critical point, beyond the value of the part to be compressed.
increment size we can try to adjust, the rule is the larger the number the more natural transition to sound, sounds more fuzzy feeling; the contrary, the smaller the number the more blunt sound, but the more clear
according to their own feelings and different audio files, they try to adjust
2, echo
select the “effect” – “echo”
talk about the role of several options
delay: The higher the number, the sound duration is longer, the stronger
volume: continuous echo of volume, not too large, otherwise affect the results
Stereo, Reverb: As the name suggests, makes echo more realistic and have a sense of space, it is generally chosen

3, equalizer
reasonable improvement is mainly the frequency structure of audio files, to achieve better sound effects.

IV: After the chapter on language
so much to start with some brief
audio now It is a lot of editing software, have announced the profession, what that simple, in fact, a lot of software, functions, and even the interface is very similar, so that a small, green audio editing software GoldWare, it is good choice
it seems a bit like advertising ……. and then introduce some GoldWare audio processing functions outside the bar ~
