Hissing from high volume

how do i get rid of hissing as if the volume is turned up high? and still keep the volume audible? what filter?
thanks

Hi A.
There are a number of audio filters built in to FCP that will help you to deal with this kind of problem audio ... for a start you might want to try either a High Shelf (or a Low Pass) filter:
Audio Filters > Final Cut Pro > High Shelf
Audio Filters > Final Cut Pro > Low Pass
You have many more options too, check out Jon Chappell's excellent introductions to the various filters available to you in FCP, their purpose and their controls here:
http://www.kenstone.net/fcphomepage/basic_audio_filterguide.html
http://www.kenstone.net/fcphomepage/basic_audio_filter_guidept2.html
Depending on how prevalent the noise is, and how well it responds to attenuation through the basic filters available in FCP, you might also want to check out the option of sending your audio to SoundTrack Pro and dealing with the issues using the far greater capabilities of that dedicated audio app:

  • Architecture/design for high volume web service calls from on Demand

    Hi,
    We have hundreds of end users (less than 600 users) that will be initiating web service calls from On Demand that will deal with both querying (stateful transaction) and inserting/updating data (stateless). Currently, we see a limitation on the number of stateless sessions (33) that can initiate web service calls. We are afraid this will lead to poor performance with the number of sessions that are allocated for stateless sessions.
    Can someone provide any design or framework information that can be implemented for high volume web service calls from On Demand? We anticipate 35K+ web service calls that will be initiated from On Demand per hour.
    Thanks.

  • Tool to export and import high volume data from/to Oracle and MS Excel

    We are using certain reports (developed in XLS and CSV) to extract more than 500K to 1M records in single report. There around 1000 reports generated daily. The business users review those reports and apply certain rules to identify exceptions then they apply those corrections back to the system through XL upload.
    The XL reports are developed in TIBCO BW and deployed in AMX platform. The user interface is running on TIBCO GI.
    Database Version: Oracle 11.2.0.3.0 (RAC - 2 node)
    The inputs around following points will be of great help:
    1) Recommendation to handle such higher volumes reports and mechanism to apply bulk correction back to system?
    2) Suggestions for any Oracle tool or third party tool

    If you were to install Oracle client software on the PC where EXCEL is installed,
    then you can utilize ODBC such that Excel can connect directly to the DB & issue SQL.

  • Hiss from creative zen 4GB using westone

    hi people,
    I have an audible hiss with the new creative zen using my WEstone UM2. The hiss starts the moment I play a track and is also present when I pause the track. The hiss is independent of the volume contol. The UM2 are notoriously easy to dri've. Can this problem be fix using a firmware? Do any of you hear this or I have a defecti've Creative Zen, ie I should bring it down for servicing.
    My UM2 detects a LOT of his from my nokia N95. A little hiss from Creative zen, ZERO hiss from my sony u8g.Message Edited by wind30 on 0-02-200705:06 AM

    Hmm, i dont see why, usually the higher the impedience, the less his you get, and get get a fabulous SNR from the Zen at 97dB 97dB SNR,. It may just not like the Zen. and you said its regardless of the volume level even if its not playing music? very odd, it may be some sort of bug? i get very little Hiss from my ZVM using 6ohm earphones (has the same SNR).
    other than that, how does the Zen sound? is the Custom Eq effecti've? did Creative finally fix the bass boost distortion? thanks

  • High volume Printing for GLM?

    I understand from various sources GLM can support high volume label output provided the correct enhancements and support packs are installed and configured.  This may include updates to WWI.  We are currently running ECC6 EHP5, SAP_BASIS 10, EHSM 3, WWI 2.7
    I would like to get this communities inputs.  Our requirement is to generate >2000 identical labels via GLM.  WWI processing today is long (5+min) and the output is large.  Ideally system would generate 1 label with indication to print 2000 times.  Our labels include barcodes and symbols and can be complex.

    Dear Richard,
    The functions of GLM is well explained as Christopher said and using GLM, you can print labels more than 10000 witha  sequential data output. To support such large quanitity of data to be printed on labels, you may need a special printers like the Zebra High volume printer. The WWI server is equipped to print large volume of labels using specific printer plugins.
    High volume printers can be used to print print requests with print files that are too large or that contain more than 32,768 labels to be printed. The HVP is designed as a printer driver for Microsoft Windows and is connected to the label printer via a plug-in.
    With the HVP, only one page with all static data is sent to the printer. The HVP then receives all of the sequential data via an interface and automatically supplements the sequential data in the printout. The HVP also integrates changing bar codes or texts in the printout.
    The Zebra 170Xi4 is one of most popular, industrial-strength printers on the market. This rugged metal unit prints 1-color labels up to 6.6" wide, with 300 dpi print resolution in thermal or thermal transfer mode. Its extra processing power equates to speeds up to 12 inches-per-second. This one is perfect for tough applications including compliance labels, product labels, and shipping labels.

  • Sender RFC adapter High volume messaging

    Hi,
    This question is related to this thread:RFC connection problem
    ERP system is sending through 1 RFC dest. (program ID) 20 requests in a minute. And PI starts to hang. ERP is not able tp sent the messages and after a while the request sent from ERP starts to get cancelled. This is a synchonous scenario. How can I handle such a high volume through 1 sender RFC adapter?

    Hello
    You can monitor the load on RFC adapter queues/threadsin the RWB
    -> Component Monitoring
    -> Adatper Engine XIP
    -> Engine Status
    -> Additional Data
    See note #791655 Documentation of the XI Messaging System Service Properties, for an explaination of the queues.
    To increase the number of threads/queues, see the blog:
    1) /people/kenny.scott/blog/2007/08/20/messaging-system-queue-properties-after-xi-30-sp19-xi-70sp11
    2) /people/kenny.scott/blog/2008/12/05/xipi-file-and-jdbc-receiver-adapter-performance-and-availability-improvements - this shows how to prevent a problem on one RFC channel blocking other RFC channels that you may be using.

  • Anyone have experience using ALE message FIDCC2 in a high volume scenario?

    Hi,
    We are evaluating the use of message type FIDCC2 to send complete FI documents from one SAP system (logisitics) to another SAP system (finance).  I'm particularly interested in throughput performance, as this will be a high volume scenario (300K+ docs per month).  Additionally, each SAP system has a customer include code block extension (CI_COBL) to BSEG, that will be carried via an IDOC enhancement (custom segment), for which we are considering using XI to map the IDOCs between the two systems.  I would appreciate any info you can share regarding use of FIDCC2 in a high volume scenario.  Thanks in advance.
    Regards,
    - Allen

    Hi Allen,
    In my past experiences, I used the message variant (EDIDC-MESCOD) and message function (EDIDC-MESFCT) to execute multiple inbound IDoc jobs to run parallel  for a given message type and IDoc type (execute program RBDAPP01 in different application servers).
    I used message variant and message function to group all sales order IDocs based on location and customer numbers. 
    You need to enter message variant and/or message function during partner profile setup (WE20). Also the middleware system (i.e. SAP XI) must maintain the above fields accordingly for IDoc inbound processing.
    Hope this will help.

  • High volumes on receiver JDBC adapter

    Hi,
    We have a RFC ->JDBC scenario where the RFC pulls huge amounts of data from R/3 and sends to XI.
    XI needs to upload this data into 5 different Db tables.Each table contains 3000-8000 records with each record containing 10-15 fields.
    When we try to run this scenario, due to high volumes of data  the JBDC adapter hangs and msgs were in 'holding/delivering' status for long time.
    Please advice on possibilities of handling this within XI.

    Hi,
    We changed the design and now we have only 'INSERT' and we don't have concerns with table refresh now.
    I am splitting the records in XI mapping as bunches on 1000 each. But I found one of the tables have more that 1lakh records.
    The data volume that we received in RFC is 150000 records(45MB). It took 7.5 mins to process this msg in Integration Engine.
    But the messages delivery into Db tables (receiver JDBC adapter processing) is very slow.At maximum it can process 250 records in minute.
    Please provide your inputs on this design. Is it Ok to accept 45MB message into XI at one shot? Even though the message got processed(splitted) in IE, they are processing in AE for long time. I believe this will have impact on other interfaces that use JDBC adapter.
    Please provide your suggestions on how to improve the design/performance of this interface.
    Thanks!

  • SQL question in a high volume web app environment

    Hi,
    We have a high volume website used in a hospital setting. When a doc selects a patient, we have to delete all previous patient history records for the patient from a certain table and insert new records retrieved from a web svc called at runtime during patient selection.
    Our 2 options are:
    Option1:
    1. Call Web svc, and always insert the results into pt_history, even if this creates duplicates (which it normally shouldn’t, if we only call every 24 hours)
    2. Only pt claims_history records that are less than 24 hours old from app method calls
    3. Nightly batch job cleans out records older than 24 hours
    Option2:
    1. Delete all existing history recs for a patient each time before calling web svc
    2. Call web svc, and always insert the results into pt_history (no chance of duplicates here)
    3. No change to existing methods
    4. No nightly batch job
    I'm leaning to option 1 to avoid contention\locks\deadlocks on the table. Any other solutions out there?
    Also any insights into which may be a better option this being a high volume transaction (several 10s of calls every sec) and table could grow to be oretty large (2 million recs and more)
    Thanks,
    JGP

    1) Why do you need to "delete all previous patient history records"? That seems contrary to the point of having patient history records...
    We want to keep these records only for 24 hrs. Older than 24 hrs is not needed.
    2) If you are just using this table to cache results from the web service call, could you use a temporary table?
    We wan to cache across all sessions for 24 hrs. So temp table would not work.
    Thanks,
    JGP

  • CRM's High Volume Segmentation with HANA without SAP BW.

    Hi,
    I'd like a clarification about the possibility of using into our CRM's High Volume Segmentatation, as Attribute List, fields and information not found on CRM system but present on HANA system and without the availability of a BW system.
    I'd like to use transactional data, such as Orders and Invoices extracted from SAP ECC which are uploaded to HANA and there used for analytical purpose in making BO's report.
    I should need to use these information in our CRM's Segment Builder to combine these selections with typical data and marketing attributes yet present on CRM system.
    I'd like to know first af all if  is it  possible this kind of Segmentation?...and then,  has someone  ever made an experience of this type? Can I get some specific documentation?
    Thanks a lot in advanced for your help.
    Best regards
    Carlo Ferro

    Hi
    The best option I think for you is to run your queries in BW
    Have these created as Infoset Queries such that CRM can then pull then as a Target Group.
    This would be about your only option I believe

  • How to handle very high volume msgs in XI

    I have  a scenario where  6 million msgs/ hour(xml) have to be picked form source and to be sent to target ,
    How do we handle this high volume of data is there any good practice
    Pls suggest .

    Hi Anubhav,
    if you just have to send source file to target system without doing any mapping, then it dont use XI for it.......because you have a very high volume of msgs and for this such load, XI will start putting your msgs in wait status and may be the JAVA engine may go down because of insufficient memory.......
    So better have an FTP utility in target system.....connect to source system by this...and move the files from source to target by this FTP utility......
    But if you have to do a mapping from source msg to target msg, then use XI....but try doing the mapping by graphical mapping and dont go for ABAP mapping to reduce memory usage for your scenario.......
    Thanks,

  • High volume of batches with Split valuation - impact on system performance

    Hi!
    I have a client that is intending to load a new material type from their legacy system which will be automatically batch managed with split valuation.  So, Valuation category will be 'x' and the valuation type will also be the batch number as automatically created on GR.
    The concern of the client is the impact on system performance.  Having up to 80,000 batches per material master record (so, 80,000 valuation types will be mainatined with a unique price in the Accounting 1 tab of the MMR) and overall around 1 million batches a year.  I'm not aware of any system performance issues around this myself but there seems to be anecdotal evidence that SAP has advised against using this functionality with high volumes of batches. 
    Could you please let me know of any potential problems I might encounter, having 1 million batches with split valuation may cause?  Logically, this would increase to tens of millions of batches over time until archived off via SARA.
    Many thanks!
    Anthony

    I currently have about 1.5 million batches with split valuation in my system (but it is not the X split), and we archive yearly.
    having many batches for one material ( lets say 1000) causes dramatic performace issues during automatic batch determination.
    it took about 5 minutes until a batch was returned into a delivery. if the user then wants a different batch and has to carry out batch determination again, then he just works for 10 to 15 minutes on one delivery.
    This is mainly caused by the storage location segment of the batches. if one batch gets movedd within a plant thru 3 different locations, then the batch has 3 records in table MCHB. But SAP has a report to reorganize the MCHB table that have zero stock.
    The X split has more effect, it is not only the batch table that makes issues in this case. With the x-split SAP adds an MBEW record (material master valuation view) for each new batch.
    However, if the design is made to get a certain functionality (here valution at batch level),   then you have to get a proper hardware in place that can give you the performance that is needed.

  • AE hooked to stereo - very high volume!  adjustable?

    I have been using an Airport Express plugged with analog headphone plug into a fairly high-end Yamaha RX-V2500 receiver. Works great.
    I just bought a 2nd Airport Express and plugged it into a much smaller, far lower end Tivoli Radio Works system. I had my iPod's dock plugged into the aux input and was using that fine. I replaced the iPod with the AE and notice that the AE-output sound is extremely high volume. I set the Tivoli's volume to maybe 3-4% and it's as loud as I'd ever listen to it normally.
    Not sure why I didn't notice this on the Yamaha - perhaps it scales down the input? Is there a way to get the AE to "quiet down" on the Tivoli? Some AE setting? Thanks.
    Is it damaging to plug the AE to analog line in on a stereo, given the volume?
    blakespot

    For the AX, the analog audio is handled by a Texas Instruments PCM2705 digital-to-analog converter which it outputs on a 3.5mm stereo minijack. It has a maximum output level of 1.53V, which is 2.3dB lower than a CD standard's 2V. The output impedance is around 15 ohms across the audioband.
    It appears that the audio input port's impedance, between your Yamaha and Tivoli, are different and why you are hearing a significant difference in volumes. The signal from the AX is not amplified, and thus, why it would require either powered speakers or a LINE in for play back.
    The AX gets is audio source, by default, from iTunes. You can adjust the output level from there.

  • Oracle database integration with SAP PI for high volume & Complex Structure

    Hi
    We have requirement for integrating oracle database to SAP PI 7.0 for sending data which is eventually transferred to multiple receivers. The involved data structure is hugely complex (around 18 child tables) with high volume processing requirement (100K+ objects need to be processed in 6-7 hours). We need to implement logic for prioritizing the object i.e. high priority objects must be processed first and then objects with normal priority.
    We could think of implementing this kind of logic in database procedures (at least it provides flexibility for implementing data selection logic as well as processed data can be marked as success in the same SP) but since PI sender adapter doesn't support calling Oracle stored procedures currently so this option is rules out. we can try implementing complex data selection using oracle table function but table function doesn't allow any SQL query which changes data (UPDATE, INSERT, DELETE etc) so it is impossible to mark selected objects in table function from PI communication channel "Update Query" option.
    Also, we need to make sure that we are not processing all the objects at once as message size for 20 objects can vary from 100 KB to 15 MB which could really lead to serious performance issues for bigger messages.
    Please share any implementation experience for handling issues:
    1 - Database Integration involving Oracle at sender side
    2 - Complex Data structures
    3 - High Volume Processing
    4 - Controlled data selection from database to contro the message size in PI
    Thanks,

    Hi,
          We can call the stored procedure using receiver adapter using ccBPM, we can follow different approaches for reading the data in this case.
    a) In this  a ccBPM instance needs to be triggered using some dummy message, after receiving this message the ccBPM can make  a sync call to the Oracle database the store procedure(this can be done using the specific receiver data type strucure), on getting the response message the ccBPM  can then proceed with the further steps.The stored procedure needs to be optimized for improving the performance as the mapping complexity will largely get affected by the structure in which the stored procedure returns the message.Prioritization of the objects can be handled in the stored procedure.
    b) In this a ccBPM instance can first read data from the header level table, then it can make subsequent sync calls to Oracle tables for reading data from the child tables.This approach is less suitable for this interface as the number child tables is big.

  • T7900 Speakers cutting out at high volume

    Help! I'm having a Party tomorrow and everytime I turned my speakers higher than about 50% they cut out, so that the volume drops until the next beat hits, then it cuts out again. I am using the original power supply, and I am sure that the connections are ok because the problem started recently.
    I did have a problem with the pendant that has the volume and bass control on it, in that there was a bad connection when tyou turned the volume dial so that it crackled and the green light dimmed, but that cleared after a little use. The green light stays on with the current fault.
    I am using onboard sound (AC97) on my MSI 875P Neo motherboard, and i haven't altered the drivers since before it worked.
    I'm running out of time before we kick off tomorrow so any help you can offer please post.
    Otherwise its going to be a very quiet party
    also i don't know why there are no paragraphs when i preview this post. Go figure

    Hello guys, I faced a similar problem with the t7900...
    when I turn up the volume from my pc... without touching anything else the speakers begins to power off and then back on,, and one time i found it powering off and on again without playing any music, that terrifed me to death.. as I was sleeping. and at last I began to check wires and just move it and I found it doing the same thing.. I found that the fuse that is located at the end of the adapter cable( the thick part located before the jack that is connected to the subw.) is not properly connected to the wire that doesn't permit high power to pass through it that is needed for high volumes so it begins to poweroff. I fixed it's and the problem never repeated again.. Hoping this to help you.
