NGWave Audio/Sound/MP3 Editor: CD Burning Part II
This is a continuation of our preparing files for CD tutorial.More adjustments
If a song is maxed out to 0db and still is too quiet, it may be time for some Dynamic Compression. Bring up NGWave's Compression (AGC) dialog, and start with the following settings:- Threshold: -3
- Hard Clip: +12 (effectively disabled)
- Ratio: inf (all the way up)
- Attack: 0.5 ms
- Release: 150 ms
- Gain: +3db
- Enhance: 0
- Soft-Knee: Yes
- Side-Chain Filter: No
- Oversampling: Yes
The recommended starting point will act more as a Soft Clip than a compressor or limiter. It allows you to get a couple extra db of loudness, without distortion or clipping. However, if you go too far with it, you will end up with a Pumping effect.
Saving the File
The final step is to save the file. Some CD burning software may convert from various file formats, but to ensure that your tracks are burned correctly it is best to save them in the appropriate file format.First, make sure the Sample Rate is 44100 Hz. If not, click Edit --> Conversions --> Convert Sample Rate and select 44100.
Second, it must be a Stereo file. If not, you can convert it using the same Conversions menu.
Finally, you want to save it as a 16-Bit PCM Wave file. Click File --> Save As, select PCM Wave for the File Type, and select 16-Bit Integer for the Attributes.
Naming Tips
The easiest way to ensure your tracks are burned in the proper order is to name the files starting with two digits. Your first track could be something like 01 - My Song.wav. Be sure to use two digits -- otherwise track 10 will sort before track 2!Conclusion
Following the above, you should be able to create CDs with consistant volume levels, and no clipping or distortion.< < Back to Tutorials
