[Tremor] Re: [Vorbis] what is max and min bitrate supported in OggVorbis?

[ravindra dwivedi]

1) What is min and max bitrate? -See In vorbis it varies acording to quality factor and quality factor range is 1-10 (1-lowest bit rate:64kbps)(10-max bit rate -498kbps)

2)What is max Audio Packet size ? -4 kB

3)What is the max size of setup header? -i think 4 kB

4)Any idea how to start for making a 24Bit fixed point reference code? Shall I start with floating point or Tremor or Tremor Low Mem Version? -better start with low mem version

5) What window sizes in Ogg Vorbis are normally supported for audio portable player? -By default for 44100 sampling frequency it takes 128  and 1024 

6) Floor0 is termed to be obsolete, Does this mean non of the commercially available encoder supports Floor0? :Floor 0 not been used because it is very complex and very slow b'coz it usees LPC in Floor 0

  Hi All, 

  I am planning to implement Ogg Vorbis Decoder on a 24 bit DSP. 

  I have following doubts: 

  1) What is min and max bitrate? 

  2)What is max Audio Packet size ? 

  3)What is the max size of setup header? 

  4)Any idea how to start for making a 24Bit fixed point reference code? Shall I start with floating point or Tremor or Tremor Low Mem Version? 

  5) What window sizes in Ogg Vorbis are normally supported for audio portable player? 

  6) Floor0 is termed to be obsolete, Does this mean non of the commercially available encoder supports Floor0? 

  Please clarify the above points if possible. 

  Thanks in advance. 

  Best Regards,
