David from New York, NY

David wants to know why he can't get HD quality for listening to streaming audio. Leo says that wirelessly, there may be some bandwidth issues. The best quality would come from a wired connection. Is he wasting his money on buying high-resolution audio? Leo says that's an interesting question. You'll get better audio with better equipment, much like what recorders and mixers use to create the audio in the first place. But the music we've been listening to is over-compressed, and we usually listen to inferior headphones that don't reproduce music well.

Mark from Grand Rapids, MI

Mark wants to know how he can convert his CDs and have them sound as good. Leo says that digital music records differently by using sampling. 44100 is CD-quality sound. 16-bit resolution is CD quality. But he can buy higher resolution samples like 24 bit. However, the files get large as a result, which is why compression has come into play. MP3, AAC, etc. Lossless is also possible with FLAC and Apple Lossless. Google Pixel XL can play back those lossless files with the right application.

Pete from Brooklyn, NY

Pete is interested in hi-res music. He wants to download FLAC music and convert it to Apple lossless. Leo says you can do that, but remember that the MAC tops out at 96 Khz, but the iPod can't play it because it's not that high, nor does it have the CPU power to process and playback hi-resolution audio. You need special hardware to play back high resolution audio. Leo says that iPods were designed for mp3s, but they can play back Apple's lossless compression at 48K x 24 bit.
