Topic: Help me understand MP3 vs. WAV

Which one is better?

Context:

I record a song on Pianoteq 8, then export as MP3 and sync it with my video performance in Premiere Pro.

I was wondering, would it sound better if I exported from Pianoteq as WAV (sample rate =44100 HZ, bit depth = 24 bits) and then synced in Premiere Pro?

Please help me understand.

Thanks,
Walid

Re: Help me understand MP3 vs. WAV

My guess is, that rendering to WAV in Pianoteq, and importing into Premiere Pro, will yield to better audio quality. The rendered file out of Premiere Pro will always have undergone some processing to the audio file, converting it to AAC, if you're exporting to the MP4 format, or something else when using other video formats.

If you give Premiere an MP3 to work with, it will also process it, and the MP3 will already have been compressed by Pianoteq, therefore it's smaller in size than WAV files. You'll be processing a processed audio file, and my gut feeling tells me that will affect the quality.

Of course you can always convert to audio/video in Premiere Pro two times for the same performance, first by starting with an MP3 audio file out of Pianoteq, then with a WAV. If you find the difference in audio quality is none, or negligible, when comparing the two final outcomes, you might be fine with MP3, just to save disk space.

WAV is uncompressed with no audio loss, whereby MP3 is compressed and is a lossy format which means some audio info has been eliminated to reduce size.
If the purpose is to make a youtube video,  import WAV audio in premiere and export the final video in premiere using  lossless format H.264 / AAC for audio, which is HD video quality with uncompressed lossless audio format  because YouTube will compress it anyway, and compressing twice an audio file is not a good idea.

Thanks for explaining that, appreciate it. Also, which of the following rendering quality would you select when exporting from Pianoteq 8?

a) Use current settings
b) Use high quality settings
c) Normalize output volumes

Re: Help me understand MP3 vs. WAV

MP3 can be used at different compression rates.
The difference between 320kbps MP3 and CD wav sound quality wise is miniscule, even through cost no object audio audiophile and pro audio systems.

To put this into context at 128 kb per second MP3 is perfectly pleasant and lots of music is fairly close in quality. If you know what you listening for you can tell it's MP3 though.
It's impressive as CD is 1411kbps wav so MP3 manages with less than 1/10th of the original data.

256 kbps blurs the line between detectable compression (by ear) and fully transparent reproduction. Swap to the slightly newer AAC instead of MP3 and just 256kbps is pretty much the same as MP3 at 320kbps.

Being a hifi nut I record at FLAC which is lossless compression. Lossless data is simply the original signal stored more efficiently. The entire audio signal is there, both audible and inaudible sounds.

So if you are using MP3 compression just choose 320.

All the music I make with Pianoteq is edited in Reaper, fhen rendered in FLAC for uploading to Hearthis or Bandcamp.
FLAC is as well allowed by YouTube.
