lowest bit rate for audio books?
|
john schwery <jschwery@...>
What is the lowest bit rate I can use for audio books without losing much sound quality? For example, when I use Baliboka to take text from an ebook.

This question usually causes a bit of controversy. In my opinion, about 64. Although many will say that for spoken material it doesn't really matter.

Probably true. You should try creating a few samples at different bitrates until you find one that suits you.

In my opinion, either 64kbps mono or 128 kbps stereo. Any lower than that,

You can use lower bit rates if you are creating a
monaural file. I'm speaking of mp3 files. I haven't read or tested
what I am saying with other files. By a monaural file, I don't mean
recording something that is monaural. I mean that you can encode the
actual file as monaural. If you want a standard bit rate, I would say not
to go below 64 monaural. If you don't care if a bit rate is standard, I
would say not to go below about 48kbps monaural. However, you can
experiment and try 32kbps. there are some audible artifacts
introduced, particularly in the way the letter s may sound but if that doesn't
bother you, you may want to use 32kbps monaural. No one can tell you
beyond a certain point, what you will or won't find acceptable. You have
to experiment and see.
Also, different people hear compressed audio
differently. I'm giving bit rates based on how I hear them. You may
find that what you find acceptable matches what I say or you may find that your
experience differs. You may want to experiment with other bit rates
because you hear compressed audio differently.
Also, keep in mind that you may hear artifacts to a
considerably more extent if you use headphones. If 32kbps sounds alright
to you when listening with speakers and you intend to listen with headphones,
evaluate the audio with headphones.

Agreed -- sometimes, 48 will provide good quality, but 64 is always

satisfactory for spoken material.

John, if you ask ten people, you will get ten different answers. For
voice quality, I am very happy with 32 K. But some will scream abuse at
you if you send them something that low. In another message I posted about
twenty minutes ago, I pointed out that by going to 32 K, I reduced the size of
the Essential iPhone training folder from 1.2.1 gigs to 124 megs, and the sound
of voice recordings is fine to my ear although many will disagree.

Hi all,
Well, this question is questionable but if it's plain mono audio 22050 should be sufficient. Ann P. -- Ann K. Parsons Portal Tutoring EMAIL: akp@samobile.net web site: http://www.portaltutoring.info Skype: Putertutor "All that is gold does not glitter, Not all those who wander are lost."

If you are using a bit rate of 32kbps, you will get
better results using 2250. If you are using 64. you should probably leave
the sample rate at the default which is something like 44100. I don't
recall the exact default number. I'm not sure which sample rate might give
better results if you use a bit rate of 48kbps. And as I said, I'm
recommending settings based on how I hear compressed audio. You may want
to check both the 2250 and the default 44100 bit rate at 32kbps and
48kbps. you may want to compare at 64kbps as well but I think at that bit
rate, you should the 44100 bit rate.

He's asking about bit rate, not sampling rate.

But for overall quality and listenability, the two are directly related.

Don, I fully agree about the 32 bit rate. I use it exclusively. If
people do not like it when I send them books they can get the books elsewhere. I
use only 1 earphone at a time anyway because many times I am doing something
else while reading.
has anyone noticed the bit rate on NLS books?

Gene, I looked in Baliboka and didn't see anything about sample rates in
the audio files settings.

I don't use Baliboka myself, but many tools
which are not dedicated audio recorders or converters may simply not
allow you to configure all audio properties.

I haven't used that program. Others may be

Carlos, I'm with you; I don't want it lower than 64. I want the reading to be clear, and if it's much lower than this, it isn't to me. If someone can hear it lower and think it sounds clear enough, then go for it.

I must respectfully disagree. I realize that this is very subjective,
but for spoken word files, 32 – 22 mono works great and doesn’t use a ton of
space. Many persons have data caps; and for example, putting those
training files at 360 K was an extremely poor choice on someone’s part.
