Batchconversion Apple Lossless 2 AAC VBR

Post by heimi »

Hi, I bought Amadeus recently to convert my Audiobooks from a lossless Format (FLAC or Apple Lossless) to a AAC Format. Because Audiobooks (especially unabrighted ones) are somewhat big, I prefer encosing them in VBR Formats. Speech has a lot of silence and VBR encoding is very efficient with Audiobooks.
In Amadeus, I cannot find a setting to encode m4a in VBR quality. Is this not possible with Amadeus Pro ?

Kind Regards
Andreas

It's not possible with Amadeus Pro nor with anything else. The
low-complexity AAC profile doesn't support variable bit rate as far as
I know.

AAC is VBR capable. You can encode in AAC VBR from iTunes.

On my Windows System I have an excellent transcoding Tool that converts from any Format to AAC VBR. It uses the Nero AAC Codec.

You are so right. I didn't know and I shouldn't have spoken out of
ignorance. Thanks for the correction.
