What commenters say

• The new AAC encoder in FFmpeg 9.1 is optimized for 48kHz audio, which is considered the standard for most applications.
• Higher sampling rates, such as 96kHz, are not necessary for consumer applications and do not provide a noticeable difference in audio quality.
• Some argue that higher sampling rates are useful for professional audio production and editing, but not for storage or playback.
• The choice of sampling rate depends on the specific use case, with 48kHz being sufficient for most applications, but higher rates being necessary for certain professional or niche uses.
• Lossless audio is not necessary for consumer applications, but can be useful for archival purposes, allowing for re-encoding with the latest lossy encoders.
• The quality of audio is not solely determined by the sampling rate, but also by other factors such as the quality of the encoding algorithm and the playback equipment.
• Some commenters disagree on the importance of higher sampling rates, with some arguing that they are necessary for certain applications, while others see no benefit.
• The perception of audio quality is subjective and can vary greatly from person to person, making it difficult to determine the optimal sampling rate or encoding settings.
