File size reduction depends on your settings and original file quality. With the 'Minimum Size' preset, you can achieve up to 90% reduction. Using mono audio instead of stereo halves the file size. Lower bitrates (64-96 kbps) are ideal for voice recordings, while 128-192 kbps works well for music.
Compression involves a trade-off between file size and quality. The 'High Quality' preset (192 kbps) preserves excellent audio fidelity for music. For voice recordings and podcasts, even lower bitrates sound great. Use the preset that matches your content type for the best results.
