Audio bitrate viewer?
As we all know there is this awesome software called Bitrate Viewer.
I want the same thing but for audio. Any ideas?

The tool I always use for my audio analysis is Audacity, and its free!
It really depends on what types of things you are looking for. Audacity has a pretty broad range of different types of analysis it can perform. |

1. Ultra correct avg bitrate (mediainfo doesn't show it correctly on some TrueHD or DTS-HD MA) 2. Awesome bitrate/time graph

are you sure? I tried File -> Open some DTS-HD MA track which is ~3GB. And it says Remaining time: 1193046:18:32 (136 years).
PS: The CPU is AMD Thuban 4200 mhz with 1600 mhz ddr3.

Well I had no idea you were going to load some gigantic audio file. Try cutting it up with some tool before loading it in.
Generally when people analyze audio, they don't analyze the bitrate, but the waveform spectrum. What exactly is it that you are trying to figure out? |

The exact file size is: 3 503 605 240 bytes or: 28 028 841 920 bits or: 27 371 915,9375 kilobits the exact duration is: 01:47:50:255 hours or: 6470.255 seconds so the exact bitrate is: 27 371 915,9375 kilobits / 6 470.255 seconds = ~4 230 kbps But mediainfo says it's 1 561 Kbps. Which is far from being right. Is there any other software which shows audio bitrate?

A lot of containers do not store timestamps for audio streams, so the bitrate graph cannot be calculated until the stream is fully decoded. This is far beyond mediainfo's job.
foobar2000 can show realtime bitrate of some audio formats, but this requires modification in decoders. |

Mediainfo is showing you the DTS core bitrate because that's what is being decoded, not the lossless DTS-HD Master track. If you can get a DTS-HD Master decoder working with directshow somehow then Haali Media Splitter can give you a graph of the bit rate, but only as you play it.

roozhou, ramicio, thank you for your replies.
Bitrate Viewer decodes the video and calculates it's bitrate. I thought maybe such software existed for audio too. Nevermind.

If the bitrate is variable wouldn't ten different audio files of the same length generally have ten different average bitrates? Wouldn't any file reporting the bitrate of a variable bitrate file report the average bitrate, or something similar? Following your link to the Bitrate Viewer program it reports min, max and average bitrates. It doesn't calculate the bitrate for a file as you just did either.

Okay then....what I meant.....
Could the bitrate being reported by Bitrate Viewer as the average bitrate actually be the mean bitrate? If I do the math for the image the OP linked to I work out the video length should be 4.182GB and not the reported 4.085GB, but maybe my math is bad. When MediaInfo reports the bitrate of a VBR audio file is it reporting the average bitrate or the mean bitrate? What about other software such as a media player like MPC-HC. Is the bitrate it reports for a video file the average or the mean? I don't know..... I've never thought about it before... it's just a thought. |

I was referring to the video in the screen shot of the program on the page which the OP linked to.
