Choosing Audio Bitrate Settings

For music, 64 (AAC)/96 (MP3) kbps is a good general-purpose setting that will sound good most listeners. This is the standard bitrate for podcasts, and it sounds great on most contemporary devices, including smart speakers and mobile devices. If bandwidth cost is a concern, you might consider using a lower setting.
c# - AAC and naudio sampling rate mismatch - Stack …

Sample rate is measured in Hz not bps. Are you sure that the AAC is 48kHz or maybe its 48kbps? In which case the sample rate could be 44.1kHz which could account for the difference. to debug this, I'd write some of the output from libfaad2 to a 48kHz WAV file and check that it plays at expected speed.

Two subtypes are defined for AAC audio: MFAudioFormat_AAC For this subtype, the media type gives the sample rate and number of channels prior to the application of spectral band replication (SBR) and parametric stereo (PS) tools, if present. The effect of the SBR tool is to double the decoded sample rate relative to the core AAC-LC sample rate.
AAC vs AC3: What’s the Difference and Which One to Choose?
https://www.videoconverterfactory.com/tips/aac-vs-ac3.html
AAC: 8 to 192 kHz. AC3: 32, 44.1, 48 kHz. Tips: The higher the sample rate the greater the dynamic range, which means more detail will be captured and the quality of the audio will be better. 2.Bit rate. AAC: 8-529 kbit/s (stereo) AC3: 32-640 kbit/s. Tips: A higher bit rate normally guarantees a better quality.

But these sampling rates discard a good amount of human audible frequencies (i.e., above 8, 11.025, and 12 kHz respectively). As a result, they are not useful for all kinds of audio. Over now to some facts about MP3. AAC ISO standardized AAC in MPEG-2 and MPEG-4 as the successor to MP3. AAC is an abbreviation for Advanced Audio Coding.

YouTube audio streams AAC files at 126kbps. While perfect for fast delivery it isn’t great for audio quality. So while there is no definitive answer with today’s large hard drives you should aim to get files at the highest bitrate possible. Audio Bitrate Comparison Lower audio bitrates achieve smaller file sizes by compressing the source file.
