I see the truth hurts. That's your shame, not my bigotry. It did work well to show what a thin skinned moron you are though.

You are a fucking mental reject who reads something, accepts it as truth and thinks everyone should agree. You are a fucking religious zealout about everything you believe to be true.

Now you are evangelizing about Opus with the same zeal of your 6,000 year old earth argument.

Hey webmaster, why don't you post an example of your wonderful opus content from said webserver which is apparently hooked up to a pay per bit meter.

I mean, let us behold the glory!

No fucking way am I going to disclose to any of you what web sites I am working with.

What purpose would that serve?

And yes, there is a bandwidth bill.

A) If I gave the information, it would not change any view or opinions.

B) It would be highly un-professional to do so, who they contract with is not something I have ever seen them publicly disclose.

C) I suspect some here are spiteful and vindictive enough to start sending things to my employer, which loves my work but it would be a time consuming hassle for them. Especially could cause problems and expense if some douche went to 4chan or wherever to inspire a DoS attack or something. I know many here simply do not like me, and some I believe would do that sort of thing.

So given A and B, why even risk C?

It would serve no purpose and would thus be a bad decision for me to make.

RE: Opus Rocks
Could be.

None of it matters to the point of this thread, that Opus is effin' cool and quite possibly is the best lossy audio codec out there for any application - be it static content or streaming, low frequency range speech or intricate music.

One codec for everything.

Oh and another cool thing - it resamples when it encodes (unless source is already at supported sample rate), so except for very low frequency samples, everything will be 48000 kHz.

Why this is good, when playing digital files, your audio is often resampled by your device if it doesn't match the sample rate your sound system is set to. That's the only way your PC (or phone or whatever) can mix sounds.

By encoding your collection with opus you can set your sound mixer to 48000 and it won't have to resample the opus files when it plays them, which is beneficial because resampling on the fly may not dither as well, but resampling on encode (if it's not already at 48000) allows for better dithering and altering gain if needed to avoid resample related clipping.

AAC/mp3/vorbis encoders generally do not resample unless you ask them too, and you will usually find some that are 44.1 kHz and some that are 48 kHz. One or the other is resampled on the fly during playback.

In fact I'm kind of curious where I said anything about transcoding or related to transcoding.

Transcoding is the process of taking an audio using one codec and encoding it in another codec, hence the term transcoding.

Where did I discuss that?

You didn't. You kept referring to transcoding as encoding, and clearly don't understand bitstreaming and embeded audio as demonstrated when you called 'DSP' as to me using fancy words.

In otherwords, I know you don't know shit.

RE: Opus Rocks
DSP is digital signal processing. That's what it fucking stands for, and DSP != audio.

DSP is the use of digital tools to process analog signals. Doesn't matter what kind of signal, could be audio or could be anaything, but it's digital manipulation of a binary representation of an analog signal.

In audio that's the PCM (pulse code modulation) part of the audio chain.

codecs are before that happens. The encoded data has to be decoded (decompressed) before DSP comes in to play.

After the opus (or aac or mp3 or whatever) has been decompressed back into PCM data consisting of samples at specified intervals THEN you can start talking about DSP.

Now one place where you could argue that that opus is not as efficient on iPhone/Android is that most of those portable devices only support 44.1 kHz and thus the 48 kHz that Opus uses has to be resampled, but quite a bit of the audio you hear on those devices is resampled, probably including any voice you hear while talking on the phone (which is undoubtedly transmitted at a much lower frequency that 44.1 kHz) so I doubt that is much of a battery issue.

But you didn't make that argument.

In fact you haven't made any argument about why opus is not efficient. You seem to believe it without evidence to back up your belief.

You kept referring to transcoding as encoding

codec is short for coder/decoder

Technically source audio that is PCM is not in a codec so encoding a wav (or AIFF) to opus or whatever is not transcoding.

Transcoding is going from one codec to another. mp3 to acc is transcoding. flac to opus is transcoding. wav to opus is encoding. mp3 to wav is decoding.

Where did I use the term differently?

RE: Opus Rocks
"To illustrate this concept, the diagram below shows how a DSP is used in an MP3 audio player. During the recording phase, analog audio is input through a receiver or other source. This analog signal is then converted to a digital signal by an analog-to-digital converter and passed to the DSP. The DSP performs the MP3 encoding and saves the file to memory. During the playback phase, the file is taken from memory, decoded by the DSP and then converted back to an analog signal through the digital-to-analog converter so it can be output through the speaker system. In a more complex example, the DSP would perform other functions such as volume control, equalization and user interface."

RE: Opus Rocks
There may be hardware MP3/AAC decoding done by the DSP chipset but lossy decoding is not DSP.

RE: Opus Rocks
"To ensure optimum performance and quality, you need to pick the right audio format and audio codec type. Starting in iOS 3.0, most audio formats can use software-based encoding (for recording) and decoding (for playback). Software codecs support simultaneous playback of multiple sounds, but may entail significant CPU overhead.

Hardware-assisted decoding provides excellent performance—but does not support simultaneous playback of multiple sounds. If you need to maximize video frame rate in your application, minimize the CPU impact of your audio playback by using uncompressed audio or the IMA4 format, or use hardware-assisted decoding of your compressed audio assets."

The Pulse Code Modulation data - that is the digital signal that is a representation of the analog waveform.

The lossy files are compressed encoded representations, no manipulation of them takes place during DSP. They have to be decoded to PCM for the DSP to take place.
