Wav is one of the containers for recording an audio stream. As a rule, uncompressed audio is recorded in wav, which makes the file size quite large. To reduce the size, you can convert the sound to a format with a higher degree of compression, or, leaving the sound in the wav container, compress it with a codec.
Necessary
- - Total Audio Converter program;
- - Adobe Audition program;
- - audio file.
Instructions
Step 1
You can recode the wav sound using the Adobe Audition editor, which, when saving the file, allows you to select the codec and compression parameters. Open the file in an audio editor and view the audio information. The window with file parameters can be opened using the File Info option from the File menu.
Step 2
Open the window for configuring the sound saving parameters using the Save As option from the File menu. If you don't have to leave the audio in the original container, select mp3 from the File Type drop-down list.
Step 3
By clicking on the Options button, choose with what bit rate and sample rate your sound will be saved. The smaller the parameters selected, the smaller the final file will be. The sound quality in it, however, will also be lower than that of the source.
Step 4
If you are trying to compress a wav PCM file and output the same wav PCM, select a sample rate lower than the original audio to reduce the size. To do this, select ACM Waveform from the Save as type list, open the settings with the Options button and select PCM from the Filter list. Select sound parameters from the Attributes list.
Step 5
The sound in the wav container can be compressed with the AC-3 codec by decreasing the bitrate. To use this codec, select ACM Waveform as the file type, click on Options and select the AC-3 ACM Codec filter. Select the bitrate and sampling rate in the Attributes list and click on the OK button.
Step 6
After configuring the settings for saving the sound, specify in the upper field "Folder" the location on the disk where the recoded file will be written and click on the Save button.
Step 7
A similar operation can be done using the Total Audio Converter program. True, this program allows you to select only the container and compression parameters, not the codec. To work with this converter, select the folder in the left window where the file is located. The contents of this folder will appear in the main converter window. Having selected one of the files, you can see its parameters in the Info field.
Step 8
In the panel under the main menu, select a container for transcoding and specify the parameters of the saved sound in the window that appears. After setting the next parameter, click on the Next button. Pressing this button after selecting the number of channels in the sound, you start the process of saving the file.
