摘要

The present document relates to audio source coding systems which make use of a

harmonic transposition method for high frequency reconstruction (HFR), as well as to digital

effectprocessors,e.g.exciters,wheregenerationofharmonicdistortionaddbrightnesstothe processedsignal,andtotimestretcherswhereasignaldurationisprolongedwithmaintained spectral content. A system and method configured to genemte a time stretched and'/or frequency transposed signal from an input signal is described' The system comprises an analysis filterbank (101) confrgured to provide an analysis subband signal from the input signal; wherein the analysis subband signal comprises a plurality of complex valued analysis samples, each having a phase and a magnitude' Furthermore' the system comprises a subband processing unit (102) configured to determine a synthesis subband signal from the analysis subband signal using a subband transposition factor Q and a subband stretch factor S ' The subbandprocessingunit(102)performsablockbasednonlinearprocessingwhereinthe magnitudeofsamplesofthesynthesissubbandsigralaredeterminedfromthemagnitudeof corresponding samples of the analysis subband sigral and a predetermined sample of the analysis subband signal' In addition' the system comprises a synthesis filte$ank (103) configured to generate the time stretched and/or frequency transposed signal from the synthesis subband signal'

LaoBiz.com is a Laos business-information and market-research platform for global companies—helping users understand the Lao market, discover opportunities and find potential partners more efficiently. Commercial records are drawn mainly from official public registry systems maintained by Lao competent authorities—including MoIC’s NED (enterprise registration), BNED (business licences) and eBRS (business registration), MoF’s TaxRIS (tax registration), and related official public channels such as intellectual-property filings. LaoBiz.com does not create or alter registry facts; on top of those official public records we organise, standardise, translate, classify by industry and index for search so fragmented filings are easier to find, understand and use. We continuously watch official public-data changes and offer sync tools so users can check an enterprise’s latest public status.
