fastest speed is only 242.5%?

Why is the fastest playback speed on 242.5%?

I'm trying to "fifty shades of grey" audiobook, which is only 130 wpm at normal speed, human can comprehend, 600 - 700 wpm. The fastest speed in rockbox can only make the book go up to 310 wpm, which is too slow for my taste.

Why?!!!!!!!

Looks like the code defines that as max:

http://git.rockbox.org/?p=rockbox.git;a=blob;f=lib/rbcodec/dsp/tdspeed.c;h=21585eb78e1d2a051a85839f887f69a2b2561fec;hb=HEAD

My guess is that this is to avoid having to buffer more data at a time, but I don't fully understand the algorithm being used.

[financialwar]

so can you change it in future releases or that is the max due to hardware limitation of the Clip+?

[saratoga]

Its not a hardware limitation, but its probably more trouble to change than most people are willing to deal with.

You really want to listen to the entirety of Fifty Shades of Grey in two and a half(*) minutes?

(*105,000(words total)÷700(wpm)÷60(s)=2.5(m))

What? Where did you learn your maths? 2.5 hours you mean?

wpm = words per minute

105000=700 = 150 minutes = 2.5 hours.

THe speed is limited to pitch it seems.

At 100% pitch, the max playspeed is 250%, at 200% pitch, the max playback speed is 500%.

Heh...math without coffee.

Anyhoo, the manual explains this limitation.

Also, the the playback speed is not remembered after shutting off...

[nick_p]

The value of the rate, pitch and speed is not persistent, i.e. after the player is turned on it will always be set to 100%. However, the rate, pitch and speed information will be stored in any bookmarks you may create (see section 8.7) and will be restored upon playing back those bookmarks.

[financialwar]

Not interested in making bookmarks. Who makes a bookmark every time they turn off their player?

[silvertree]

Rockbox can make bookmarks automatically upon shutdown and it can do it for files/folders that only have existing bookmarks so it doesn't interfere with music listening.

I don't know what bookmarks is for? What is the point of bookmarks? The player resumes where I turn it off.

Sounds too complicated for a simple function. Just remember my speed and where I left off.

[nick_p]

What is the point of bookmarks?

In your case, to remember your speed where you left off.

Unless you'd like to dig into the code and make it a persistent setting, but I'd wager that'd be more complicated in the short term.

Is the development still going on or this is the end of rockbox? Why are you asking an average user to program? This is not my job! I can donate money to rockbox if that's what you like. But I was recommended by many to use rockbox, but it lacks this basic feature.
