Converting files to wav with SS 3.4

[VanJay011379]

Hi,

I am using Sonic Stage 3.4 to copy files from my HiMD minidisc to my computer to burn to discs.

However, I have a question about transferring the files.

Before transferring, I looked at the properties box. In the advanced box, it has the opportunity for a bit rate choice. I transferred many at 64kbps. I bumped it up to 352 kbps and didn't notice a a large difference in the spectral view between the 64 kbps and 352 kbps wav files in Exact Audio Copy.

Is there a difference in the kbps used?

Cheers,

Chris

What mode are you recording in? There's not much sense in bloating a low bitrate file to a higher bitrate, you won't gain any quality, in fact you will loose some. If you've recorded uncompressed (PCM) and encode to a lossy mode, you will get lower quality the lower the bitrate. The threshold of good quality is up to every individual's own hearing and cannot be judged by spectral graphs. They tell virtually nothing about perceived sound quality.

Do you want to create ATRAC CDs (compressed) or plain Redbook Audio CDs? For Audio CDs, don't convert to a lossy bitrate before transferring, it will be decompressed eventually and you just lose quality.

I'm not recording in PCM but in the next mode. I am using standard minidiscs and can record about 2 hrs and 36 mins in the setting. I think it is HiMD setting.

You're recording in Hi-SP, which is 256 kbps. I suggest using the option to upload "As Is." That will mean the recordings on your computer, played back through SonicStage, are the same quality as the ones on the disc. If you force them to 64 kbps they will be lower fidelity.

The more kbps--kilobytes per second--the more digital information the file has to recreate the sound. At 64 kbps, there is a definite decrease in fidelity.

When you convert those uploaded recordings to .wav, they will preserve all the quality they had, because .wav is lossless: It keeps all the information that was there. The .wav files are 1411 kbps, which means they will be considerably bigger, but if you burn them onto a CD, they will play in a CD player.
