similar to: Speex WBB decoder on AT91SAM7S microcontroller?

Stripping out usused stuff is very easy, especially with static libraries. The only thing that could cause problem is the speed of the CPU. It's very hard to say what the requirements are because it depends a lot on the exact CPU you're using and (for ARM) the configuration of the cache and the speed of the bus.

Good afternoon! Thank you for your product Speex. We want to use it in microcontroller AT91SAM7S256 (48 MHz). We applied the following: #define FIXED_POINT #define DISABLE_WIDEBAND #define DISABLE_HIGHPASS #define MANUAL_ALLOC #define OS_SUPPORT_CUSTOM at speex_encoder_init(&speex_nb_mode); speex_decoder_init(&speex_nb_mode); tmp=2; speex_encoder_ctl(st, SPEEX_SET_QUALITY,

I'd strongly advice to use a higher performance micro. Let's consider that you'd succeed in getting it working right after optimizations. The time you want to add other speex features or other

Hi all I'm looking in to using speex for an ARM7 based speech decode development (note we need the decode only). My hope is that we should be able to run the decoder (in wideband mode) real time on the ARM7 (40MHz) without any problems (the difficulty would be in the encode - but we plan to run that offline on a PC - so we should be OK). Can anyone confirm that this is the case please? Also

Hello, I'm sorry if this is not the correct place to ask this question but what I'm looking for is any data on the reality of Speex working on an ARM7 core? I'm looking at doing a few diffrent projects where I will be using a proc such as the LPC2378 with the ARM7TDMI-S core running at 72Mhz (although errata show only 60Mhz is currenlty possible). Do you know if there is a port

?Hi, I was wondering if anyone has managed to get the preload_app and SIGUSR2 combination working well with upstart? My issue currently is that when I perform a SIGUSR2 against the master, check everything''s working and close off the old master, upstart then attempts to restart it because the original PID/binary are no longer running. What is the correct way of handling this? In my

Hi It seems that survfit() doesn't accept the argumnet 'error' as below >survfit(fit, error='greenwood') Error in survfit.coxph(fit, error = "greenwood") : unused argument(s) (error ...) Isn't is allowed to do that for a coxph object? Regards Soren Windows XP, SP2 R 2.3.0

Interested in building a speex codec (basically audio <-> speex <-> data stream) using TI's small MSP430 microcontroller. Is there any way to estimate feasibility based on CPU requirements? Example - speex is happily encoding on an old Pentium-1 processor (166 MHz) using about half the CPU (as reported under Linux); the TI microcontrollers are much slower yet (8-16-25 MHz) and

Well, the first question is whether you want encoding, decoding, or both. If there's one you don't need then you can remove that (unfortunately, there's no easy way right now). Even if you need both, then you can

Sounds like a job

Hi all, thanks a lot for your replies! Sorry for my typo, the flash size is 8MB (Byte) :-) Unfortunately I cannot use another flash because I'm working on a proprietary board. Jean-Marc, thanks for your suggestions. I thought to use fixed point for convenience, but I can work on floating point too, so I will take in account the codec2 (I didn't know it). Moreover, if you all have

Hi, First of all, I'm quite new to opus. I'm trying to use fixed point opus on an ATMEL AT32UC3B0512. I added the opus source into mine sw tree, I trim off code I don't use (eg. arm, x86 folders) It compiles, but the generated image is too big to fit in the flash. Have I any way to reduce the source footprint? (Eg. throw away unecessary files, if there are any..) Thanks, Daniele.

Some switch hardware can generate the packets directly, negating the need for a box on every VLAN. Meraki hardware can do it, but you have to go through the dashboard so automating it isn't currently possible. Here is some documentation on forwarding WoL on catalyst 3750 switches from Cisco:

Hello Daniele It would be worthwhile to attach an external serial flash or USB thumb drive, if the intent is store data. This allows for far more flexibility in storage Regards Amit On Fri, Aug 26, 2016 at 11:02 AM, Jean-Marc Valin <jmvalin at jmvalin.ca> wrote: > On 26/08/16 11:40 AM, Daniele Barzotti wrote: > > You're right!

Hi, I'm evaluating the libspeex library for usage in an embedded platform based on an ARM7 TDMI micro (the ubiquitous Atmel AT91SAM7S). In details, I'm trying to use libspeex to encode the audio stream coming into the micro from an I2S channel and saving the encoded audio to an SD card (currently in binary format just to test it decoded back to the I2S channel from the saved file), but

Hi Tom Thanks, just at the feasibility phase right now, so this sort of info is really useful. Memory/MHz values for the Tremor/Vorbis code seem to vary wildly - at least I could not find a consistent set of numbers after trawling through the discussion groups...
