AIFF to SPX Quality Analysis
For audio-to-audio conversions, Xonvert applies format-aware algorithms that respect the unique characteristics of both AIFF Audio and Speex Audio. Converting within the same category means most properties transfer naturally. Sample rate and bit depth are preserved during conversion. If the target format has limitations, Xonvert downsamples using high-quality dithering algorithms. When converting from AIFF Audio to Speex Audio, some quality trade-off occurs due to lossy compression, but Xonvert uses optimal settings to minimize any visible degradation.
Audio conversion from AIFF Audio to Speex Audio focuses on preserving sonic fidelity while adapting to the target format's characteristics. Moving from lossless AIFF Audio to lossy Speex Audio reduces file size dramatically. At typical quality settings (128-256 kbps), the compression is psychoacoustically transparent — most listeners cannot distinguish the output from the original. Sample rate, bit depth, and channel layout are preserved when supported by the target format.
Compression trade-off: Your lossless AIFF source retains all original data. Converting to lossy SPX will reduce file size substantially, but some data is permanently discarded. Use the quality slider to balance file size against fidelity.
Bitrate consideration: For lossy SPX output, Xonvert defaults to a high bitrate setting that preserves audio transparency. You can adjust the bitrate in the settings panel — higher values mean better quality but larger files.
