dsf to wav : what CPU power ?

[chip]

Hi all,
Sonore ask me to perform some additional test so I just posted this following on their forum.

Hi,
Music Library
MinimServer 0.8.4 update 88
MinimStreamer 0.5.2
stream.converter ffmpeg314
Bubble UPnP Server Version 0.9-update21

Control Point
Samsung Galaxy Tab S2 tablet
BubbleUPnP version 2.8.3.1

Renderer
Sonore Signature Rendu shown as Audio Render-143 (OpenHome)

DAC
PS Audio DirectStream DAC

NativeDSD downloads used for testing
Sarah Vaughn - Live at Rosy's
DSD64 - 09 A-Tisket, A-Tasket.dsf
DSD128 - 09 A-Tisket, A-Tasket.dsf

MinimStreamer stream.transcode values and results from 2016-12-08 testing requested by Sonore

MinmStreamer stream.transcode value <empty, no values> and restart server
DSD64 file
PS Audio displays - Input: DSD Rate: DSD64 1 bit
BubbleUPnP displays - DSF | 2822.4 kHz | 1 bit
DSD128 file - small spike before playback
PS Audio displays - Input: DSD Rate: DSD128 1 bit
BubbleUPnP displays - DSF | 5644.8 kHz | 1 bit
This plays back as expected with only a small spike when changing from DSD64 to DSD128.

Clear BubbleUPnP playlist
MinmStreamer stream.transcode value "dsf:dopwav" and restart server
DSD64 file - small spike before playback, switching from DSD128 to DSD64
PS Audio displays - Input: DOP Rate: DSD64 1 bit
BubbleUPnP displays - WAV | 176.4 kHz | 24 bits
DSD128 file - small spike before playback, switching from DSD64 to DSD128
PS Audio displays - Input: DOP Rate: DSD64 1 bit
BubbleUPnP displays - WAV | 352.8 kHz | 24 bits
Playback of this track sounds like it is at half speed
The PS Audio does not playback 352.8 kHz files - incorrect see next post
The time slider on BubbleUPnP moves to 100% but timer keeps counting until 3:39 but the track is only 1:49 long
The DSD64 file plays back as expected but the DSD128 file does not playback properly

Clear BubbleUPnP playlist
MinmStreamer stream.transcode value "dsf:wav24;176" and restart server
DSD64 file
PS Audio displays - Input: PCM Rate: 176.4k 24 Bits
BubbleUPnP displays - WAV | 176.4 kHz | 24 bits
DSD128 file
PS Audio displays - Input: PCM Rate: 176.4k 24 Bits
BubbleUPnP displays - WAV | 176.4 kHz | 24 bits
Both playback as expected without spikes


Is this the test you wanted me to perform?
Do my results help you identify the issue?

Please advise,
Chip
