FAQs About AAC Compression

Q1. Does compressing the AAC file change the encoder?

No. Because you only lower the audio bitrate to compress your audio files. You didn't convert it into a new audio format, such as MP3, etc. So, if you compress the file, the encoder will not change unless converted into a new format.

Q2. Does compressing the AAC take longer to process?

Actually, it depends on the compressor you are about to use and the size of the audio file; compressing speed will always depend on the compressor of your choice. If you want software that supports fast compression and batch conversion, just give HD Video Converter Factory Pro a try. It is the pro version of Free HD Video Converter that can bring you more features.
